Liz Truss' parliamentary constituency of South West Norfolk could change to take in parts of Cambridgeshire under new proposals.

The Conservative strong-hold could be renamed Thetford and Downham Market and the boundaries moved to include Littleport West and East across the border.

The proposals are part of a planned reduction of the size of the House of Commons from 650 to 600 MPs. Norfolk would not lose any constituencies although some minor changes to boundaries have been recommended.

The plans are also aimed at ensuring that the number of voters in each constituency is equal. The Boundary Commission for England has been tasked with making independent recommendations about where the changes in the East of England should be.

An initial 12-week consultation was held in the autumn last year, giving the public the first chance to view and comment on the plans, followed by a second consultation in the spring of this year. More than 25,000 public responses were received across the country.

People can go to the Commission's website, www.bce2018.org.uk, to view the latest plans.

The next, and final round of consultations, ends on December 11. The final recommendations will be submitted to parliament in September 2018.

If agreed by parliament, the new constituencies will be in use at the next general election.

Sam Hartley, secretary to the Boundary Commission for England, said: 'We're delighted with the huge number of comments on our initial proposals that we've received from members of the public, many of which contain valuable evidence about people's local communities. 'Based on what people have said to us, we have revised more than half of our initial proposals. But we still want people to tell us what they think of this latest map.'

But the proposals appear unlikely to be approved by parliament after Theresa May lost the Conservative majority in the Commons as the plans would face stiff opposition from other major parties and disgruntled Tories who stand to lose their seats.

The Democratic Unionist Party, whose 10 MPs Mrs May relies on to have a majority in the Commons, are unlikely to support moves which could see their representation at Westminster cut.
