Exhibit No.4

3 January 2006

COOKSON GROUP PLC

SALE OF SPECIALTY COATING SYSTEMS ("SCS") FOR $55.5M

GBP100M DISPOSALS PROCEEDS TARGET NOW ACHIEVED

Cookson Group plc ("Cookson"),  the leading materials science company, announces
that on 31  December  2005 it sold  SCS,  a  business  which  forms  part of the
Assembly  Materials  sector of Cookson's  Electronics  division,  to Bunker Hill
Capital for US$55.5 million (GBP32.3 million*).  The consideration was satisfied
by way of an immediate cash payment of US$54.0 million (GBP31.4 million*),  with
an additional  US$1.5 million  (GBP0.9  million*) to be paid upon closing of the
sale of the SCS China business in early 2006. The consideration  will be subject
to  completion  balance  sheet  adjustments  in respect of working  capital  and
capital expenditure, which are not expected to be material.

The sale of SCS is part of  Cookson's  strategy of  achieving  progressive  debt
reduction through, in part, non-core business disposals, and brings the proceeds
from disposals  agreed in 2005 up to the GBP100  million  targeted by the end of
2006.

SCS comprises a group of companies and business  assets with its main operations
in the USA,  Europe  and  Asia-Pacific.  Its  primary  business  is the  service
application of a specialty  conformal  coating  product  principally  for use in
automotive, electronic and medical applications.

On an International  Financial  Reporting Standards ("IFRS") basis, for the year
ended 31 December  2004,  SCS generated a trading  profit** of GBP4.3 million on
revenue of GBP19 million.  As at 31 December 2004, SCS had gross assets of GBP18
million and gross liabilities of GBP2 million.  For the six months ended 30 June
2005,  SCS  generated a trading  profit**  of GBP2.1  million on revenue of GBP9
million.  As at 30 June 2005,  SCS had gross  assets of GBP19  million and gross
liabilities of GBP2 million and employed 285 people.

The net cash proceeds from the sale will strengthen  Cookson's balance sheet and
provide  greater  financial  flexibility.  Additionally,  Cookson will  consider
making  advanced  payments  into its UK pension  scheme to reduce  the  existing
deficit.

In January 2005,  Cookson announced a target of raising over GBP100 million from
disposal  proceeds by the end of 2006.  In the six month period to 30 June 2005,
proceeds from disposals totalled GBP13 million.  Furthermore,  on 15 December it
was  announced  that a  conditional  agreement  had  been  entered  into to sell
Cookson's  Laminates business for US$91 million (GBP53 million*).  On completion
of that disposal (expected in February 2006) together with some further property
disposals  completed  recently and including the proceeds from this transaction,
Cookson will have generated disposal proceeds of over GBP100 million.

Commenting  on the sale of SCS,  Nick Salmon,  Chief  Executive of Cookson Group
plc, said:

"SCS is a good quality business, as reflected in the price achieved. However, it
does not fit  strategically  with our core  electronics  business,  and the sale
represents further significant  progress in terms of our strategy of progressive
debt  reduction.  Following  the recent  announcement  regarding the sale of our
Laminates  business,  this deal means we have  achieved  our  strategic  goal of
raising GBP100 million through disposals, a year ahead of schedule.

"Our  strategic  plan  also  involves  achieving  significant   improvements  in
profitability,   and  our  third  quarter   trading  update  in  early  November
demonstrated that we are making solid progress in this regard as well."

Note to editors:

In January 2005,  Cookson  announced its strategy  which focuses on  performance
enhancement, debt reduction and the disposal of non-core activities.

Cookson's  objectives include improving  profitability,  with targeted return on
sales by 2007 of 10% in both the Ceramics and Electronics divisions and a return
on net sales value (i.e.  excluding the precious  metals content) of 15% for the
Precious Metals division.  Cookson also plans to reduce total debt significantly
over the next 2-3 years.  This will be achieved  through a combination of strong
operational  cash  flow  -  from  improved  profitability  and  working  capital
management - and a disposal  programme which will raise over GBP100 million from
the sale of a number of non-core  activities  and assets by the end of 2006.  In
addition,  Cookson intends to resume a sustainable  dividend  payment as soon as
possible with dividends funded from free cash flow.

COOKSON GROUP plc - FOURTH QUARTER TRADING UPDATE

Cookson Group plc ("Cookson"), the leading materials science company, is issuing
this  trading  update  ahead of its full year  results for 2005,  scheduled  for
announcement on 14 March 2006.

Fourth Quarter Highlights:

o    Better than expected trading performance from the Ceramics and Electronics 
     divisions; Precious Metals division's weak trading continued

o    Disposal proceeds target of GBP100 million reached ahead of schedule

o    Recently announced disposals:

     - Disposal of Laminates business for US$91 million (GBP53 million*)

     - Disposal of SCS for US$55 million (GBP32 million*)

Commenting on the fourth quarter, Nick Salmon, Cookson's Chief Executive, said:

"We continue to make good progress in implementing  the strategic plan announced
last  January.  Fourth  quarter  trading  has  been  ahead  of the  expectations
indicated in our 4 November Trading Update, due to strong  performances from our
two largest divisions, Ceramics and Electronics. The full year results will show
that these divisions, post the disposals, have made substantial progress towards
achieving the targeted margin levels.  With the two disposals signed in December
we have now reached our disposal target of GBP100 million."

Trading

The Ceramics  division  performed  significantly  ahead of  expectations  in the
fourth  quarter with steel volumes in Europe and the USA better than  previously
anticipated and a robust  performance from the Glass sector.  Trading profit for
the fourth quarter is now expected to be higher than that recorded for the third
quarter.  Trading in our Electronics division was also ahead of expectations due
to a strong performance from the Assembly Materials sector,  benefiting from the
continued pick up in the lead free solder market.  The Precious  Metals division
continued to experience  weak market  conditions,  most  particularly in the UK,
with a weaker seasonal up-tick than in prior years.

The  Group  now  expects  its  overall  performance  for 2005 to be ahead of its
previous expectations.

Cash generation for the fourth quarter has been satisfactory,  although the year
end net debt level has been negatively  impacted by the  strengthening of the US
dollar.  Overall net debt at 31 December  2005 is expected to be slightly  below
GBP300 million.

This includes the SCS disposal  proceeds of GBP31.4 million received at the year
end but has been negatively  impacted by an approximately GBP32 million exchange
rate movement effect in the year.

Restructuring

During the fourth quarter several new  restructuring  initiatives were launched,
targeted  at  reducing   operating   expenses  and  exiting  certain   commodity
activities.  The  related  charges  will be  booked  in 2005,  taking  the total
restructuring  charge in the year towards GBP20 million.  The cash spend in 2005
relating to these  initiatives,  plus those launched in previous  years, is also
expected to be approximately GBP20 million.

Disposals

In January 2005,  Cookson announced a target of raising over GBP100 million from
disposal  proceeds  by the  end of  2006.  The  disposal  programme  is  part of
Cookson's  strategy  of  focussing  on higher  technology  products  and exiting
commodity activities, as well as achieving progressive debt reduction.

On 15 December  2005,  the  disposal of Cookson's  Laminates  business for US$91
million (GBP53  million*) was announced which is conditional upon clearance from
the  competition  authorities  in Europe.  Due to some delays by the acquirer in
submitting the merger filings, this clearance is now not expected before the end
of March 2006.  In addition,  on 3 January 2006  Cookson  announced  that it had
disposed  of its SCS  business on 31 December  2005 for US$55.5  million  (GBP32
million*).  On completion of the  Laminates  transaction  and including the cash
proceeds  from  property  and other  disposals  in the twelve month period to 31
December  2005,  Cookson will have  generated  disposal  proceeds of over GBP100
million.

Laminates  and SCS will be reported  as  'discontinued  operations'  in the 2005
financial statements.

Pension Deficit

The  reduction  in  December  in the long term  corporate  bond rate used in the
calculation  of UK pension  fund  liabilities  means the  pension  deficit  will
increase over the amount stated in the Interim  Results.  A full  revaluation of
the UK pension  scheme is not yet  available  but we expect the  increase in the
deficit between 1 July and 31 December 2005 to be in the order of GBP20 million.

Other

The  Company's  Extraordinary  General  Meeting  on 12  January  will be seeking
shareholder  approval for changes to its Articles of  Association as part of the
planned  termination  of the  registration  of its ordinary  shares with the USA
Securities  and  Exchange  Commission  and to  effect a  reduction  of its share
capital.

Cookson  expects  to  announce  the  preliminary  results  for the year ended 31
December 2005 on 14 March 2006.

Exhibit No.8

12 January 2006

                                Cookson Group plc

                    Results of Extraordinary General Meeting

Cookson  Group plc  ("Cookson"  or the  "Company")  announces  that the  special
resolutions  proposed to holders of the  Company's  ordinary  shares of 10 pence
each  ("shareholders"),  and as detailed in the circular sent to shareholders on
19 December 2005, were duly passed at today's Extraordinary General Meeting. The
resolutions were:

- to amend the Company's  Articles of Association  to facilitate  termination of
its registration with the US Securities and Exchange Commission ("SEC");

- to  reduce  the  issued  share  capital  of  the  Company  by  cancelling  and
extinguishing the deferred shares of 49 pence each;

- to reduce the  authorised  share  capital of the  Company  by  cancelling  and
extinguishing six ordinary shares of 1 pence each; and

- to cancel the share premium account of the Company.

The  amendment to the Articles of  Association  includes a provision  conferring
upon the Board the power to require  ordinary  shares which are held directly or
indirectly by US resident  shareholders to be sold in order to reduce the number
of  such  shareholders  to  below  300,  as  presently  required  by the SEC for
termination of  registration.  In order to avoid the costs of complying with SEC
registration  requirements  in respect of the  financial  year ended 31 December
2005,  the Board  intends  to  commence  exercising  these  compulsory  transfer
provisions as soon as reasonably  practicable.  Subject to legal,  fiduciary and
regulatory  requirements  and costs, the Board will take account of the relative
size of the  holdings of US resident  shareholders  and apply the power first to
those US resident shareholders with the smallest holdings of ordinary shares.

Subject to approval by the High Court,  cancellation  of the deferred shares and
the other  reductions of capital outlined above are expected to become effective
on or around 15 February 2006 upon  registration  of the order of the High Court
with the Registrar of Companies.

Copies of the  resolutions  passed at the  Extraordinary  General  Meeting  will
shortly be  available  for  inspection  at the UK Listing  Authority's  Document
Viewing Facility, which is situated at:
