Changes made to boundary proposals

Boundary Commissioners have reported changes to sweeping proposals for parliamentary constituencies aimed at cutting the number of MPs by 50 to 600.

However, the scheme faces stiff opposition in the House of Commons next year with Liberal Democrats - angered by Tory backbench rejection of Lords reform plans - vowing to vote against it.

The latest alterations make little difference to prospects of Westminster's "big beasts".

Deputy Prime Minister Nick Clegg sees his current constituency name incorporated in the new Sheffield Hallam and Penistone although it covers the same area as in last year's original report by the Boundary Commission for England. In May's council polls Liberal Democrats still had a majority there despite sweeping losses nationwide.

Veteran Tory Cabinet Minister Kenneth Clarke now sees his Rushcliffe, Nottinghamshire, constituency dispersed to four others, one of which crosses the border with Leicestershire.

Changes in Leeds leave two potentially safe Labour seats at Leeds South East and Castleford and Leeds Metropolitan and Ossett.

This may mean that shadow chancellor Ed Balls, whose current seat is marginal, would find a safe powerbase without having a selection battle with his senior Labour colleague Hilary Benn.

There was cheer for Chancellor George Osborne, with the name of his current Tatton constituency returning to commissioners' maps after being removed last year.

New shadow business secretary Chuka Umunna - whose south London Streatham constituency would have been broken up in original boundary plans - will be relieved that amendments have brought in a new Clapham and Streatham seat, most of which covers areas from his existing powerbase.

There will be a further round of consultations by the commission before the proposals have to be submitted to Parliament next October.
