Not only has Tony Blair reshuffled his cabinet but the names and responsibilities of key departments have been changed. These are the principle changes:
John Prescott's Department for Environment, Transport and the Regions becomes the Department for Transport, Local Government and the Regions (DTLR). Stephen Byers takes control of the new department, which has responsibility for planning, building regulations, transport and local regeneration. Prescott remains deputy PM.
Responsibility for environment passes to the new Department for the Environment, Food and Rural Affairs (DEFRA), which replaces MAFF. Margaret Beckett heads the department, replacing Nick Brown, who returns to the backbenches.
Responsibility for construction passes to the DTI.
A minister for construction was still undecided as the AJ went to press.
Tessa Jowell replaces Chris Smith at the Department for Culture, Media and Sport (DCMS).
Alan Howarth is replaced by Lady Blackstone as arts minister at the DCMS.
Kate Hoey loses the sports brief and is replaced by Richard Caborn.
Nick Raynsford - formerly minister for housing, construction and planning - is now local government minister at the DETR.
Lord Falconer retains responsibility for the Millennium Dome and becomes minister for housing and planning.
Michael Meacher remains environment minister.
Hilary Armstrong moves from housing to become Chief Whip.
