The political map of Leicestershire is set to be redrawn in one of the biggest shake-ups for decades.

Half of the county's 10 constituencies are set to change following a review by the Boundary Commission, which aims to cut the number of MPs from 650 to 600 by 2015.

Under the plan, revealed today, Rutland and Melton, Loughborough, Harborough, Leicester South and Leicester East would not change, but the remaining constituency boundaries would all be altered.

North West Leicestershire constituency would be split into two.

Andrew Bridgen, the constituency's Tory MP, said: "The thought of having this constituency carved up is regrettable.

"Constituencies spread across county and district boundaries are likely to make casework a lot harder for MPs.

"However, I voted for a reduction in the number of MPs and I stand by that."

One half of the constituency, including Coalville, will join with Nottinghamshire's Rushcliffe to form a new constituency called Coalville and Keyworth.

If the change goes ahead, current Rushcliffe MP Ken Clarke could potentially challenge Mr Bridgen to stand as Tory candidate in the new constituency at the next election.

Lutterworth would be moved from South Leicestershire, represented by Andrew Robathan, to the Daventry constituency, in Northamptonshire.

The remainder of South Leicestershire would be renamed Blaby and contain all but three wards in the district of Blaby, as well as Earl Shilton.

Tory Mr Robathan said: "I support the reduction of MPs – if I had it my way I'd cut the number to 500.

"However, I'm disappointed at the plans to cut the Lutterworth area from my constituency, as that's where I live."

Leicester West, represented by Labour's Liz Kendall, would expand to incorporate the Millfield, Ravenhurst and Fosse and Winstanley wards of Blaby.

Ms Kendall said: "I cautiously welcome the changes, given the mandate of the Boundary Commission was to reduce the number of constituencies.

"However, I do feel that the number of Labour seats will be reduced as a result."

The Charnwood constituency, represented by Tory Stephen Dorrell, would be renamed Mid Leicestershire and have three wards from the Bosworth constituency added to it.

The remainder of Bosworth, whose MP is Tory David Tredinnick, would be extended north to include Ashby and the surrounding area.

Colin Copus, local government professor at De Montfort University, said the planned changes were significant.

"The size of the constituencies will be very similar, but it means that in many cases we're losing the link between constituencies and local authority areas.

"We've also got strange situations where an MP will be representing areas with very different identities because they're in different counties."

But he added: "I don't see any major political winners or losers in this."

MPs and other interested parties will be able to "appeal" against the commission's provisional findings as part of a 12-week consultation process.

After considering these arguments, the commission will then release a revised plan, which itself will be subject to extensive consultation.

The final plan must be submitted to Parliament by October 2013 to be in place for the next election, scheduled for May 2015.
