This is the first public affairs agency hire by the firm and has been taken to improve links within central and local government and the NHS.
The health service is seen as a particular area of involvement for Sun, following recommendations in last year's report into NHS funding by former NatWest CEO Derek Wanless, which called for a doubling of NHS IT budgets.
In reference to the Wanless report, Sun's government sales manager Graham Kemp said: 'It would seem that the Government would be open to speaking to Sun regarding this area and we want Bell Pottinger to help us make sure we are speaking to the right people.'
Local government is also a key area as the Government has issued a 2005 deadline of take up of e-government by local authorities.
The BPPA team is led by MD Peter Bingle, who reports to Kemp, and includes associate director Howard Dawber, account director Malcolm Gooderham and consultant Oliver Bates.
