TDC Switzerland to reduce workforce by 145 employees.

TDC Switzerland will reduce its workforce of 2,524 employees by 145,
corresponding to 5.7 pct., through a redundancy program. The aim is to
strengthen TDC Switzerland's position in the Swiss telecommunications market by
adjusting the cost structure to the competitive environment. The reduction of
145 employees affects all business units, although the reduction primarily
affects employees with no direct customer contact, so that TDC Switzerland can
maintain the usual quality of customer service.

"TDC Switzerland's promise to the market is that we offer the best value
proposition to our customers. This step is imperative in order for us to
continue to do so. We are convinced that in this way we can even further
strengthen our position in the Swiss telecommunications market," says Jesper
Theill Eriksen, CEO of TDC Switzerland.

In collaboration with employee representatives and labour unions, TDC
Switzerland has created a social compensation plan. This includes primarily
support in terms of full wages for a period of up to 12 months, depending on
age, length of service and personal circumstances, for the employees affected.

The total costs associated with the workforce reduction are estimated at
approximately CHF 15m pre-tax (corresponding to approximately DKK 72m). The
total costs will be expensed as a special item in the second quarter of 2006.
The saved wages in 2006 following the workforce reduction have been incorporated
in the previously announced outlook for TDC Switzerland for 2006, cf. TDC'
quarterly report for first quarter of 2006.
