In the ministerial reshuffle following the resignation of transport secretary Stephen Byers, schools minister Stephen Timms has been named as the successor to CSR minister Douglas Alexander.
Alexander was moved in the reshuffle from the Department of Trade and Industry post to the Cabinet Office.
Timms also takes over Alexander's other duties of e-commerce, communications and information, postal services, consumer goods and social enterprises.
He is seen as a particularly sensible choice to take over the telecoms side of Alexander's remit as he has more than 20 years' experience in the sector. This includes eight years each working at IT company Logica and analyst group Ovum.
He also has five years' ministerial experience, including stints at the Department for Education and Employment, Department for Social Security and the Treasury.
Commenting on his appointment, IPR president Jon Aarons said that whatever Timms' experience it was disappointing that he is the third person to fill this role in such a short time.
He said: 'Alexander was making his mark and now he's been moved. I would like to have seen more consistency.'
The first CSR minister was Kim Howells who took it as part of his remit in 2000. He was replaced last year by Alexander.
In a separate development, the DTI has reshuffled its three-strong e-commerce and CSR PR team following the promotion of senior press officer Marcus De Ville, to the DTI's communications management team.
He will be replaced by PRO Kierstan McDonald. PROs Bradley Smythe and Nic Fearon remain on the desk.
