A rebranded Department of Trade and Industry (DTI) is among Tony Blair's reshuffle announcements for his new government.

The heavily criticised DTI has been renamed the Department for Productivity, Energy and Industry (DPEI) and will be headed by Alan Johnson, previously Pensions Secretary.

The government claims the reason behind the change is to introduce more focus on business productivity.

The DTI received considerable criticism during the election campaign for the level of bureaucracy it imposes on businesses.

The Liberal Democrats promised to abolish it if they came to power while the Conservatives pledged to reduce it in size.

Tony Blair acknowledged the debate when he announced the new department.

"There has been much debate about the future role of the Department of Trade and Industry in recent months. The government continues to believe it has an important role to play. The Department will be refocused and reinvigorated playing a greater role on productivity," he said.

A DPEI spokesperson said officials were waiting for the appointment of ministers to the department before they could say what effect this would have on policies such as the Small Business Service. He also could not confirm whether there would be any job cuts within the department.

It is expect that other appointments to the new department will take place early this week.

Alan Johnson's departure from the Department of Work and Pensions has made room for the return of David Blunkett. Blunkett has already hinted compulsory pensions may be introduced as a means to solve the UK's pensions troubles.

Ex-DTI boss Patricia Hewitt was tipped for the job by some sources but she now heads up the Department for Health.

Former Health Secretary John Reid takes the job of Secretary for Defence, while his predecessor Geoff Hoon has become the Leader of the Commons.

Alistair Darling remains as Transport Secretary and Ruth Kelly keeps her role in education.

Margaret Beckett is still the Environment minister and John Hutton has been made the Chancellor of Lancaster.

The top jobs of Foreign Secretary and Chancellor have remained the same with Jack Straw and Gordon Brown respectively.
