A new group of peers to review the size of the House of Lords is to be announced on Tuesday.

The Telegraph understands that the committee will look options to reduce the number of peers to around 600, which will be the size of the House of Commons after the next general election.

A statement confirming the changes is expected to be made by peers in the House of Lords on Tuesday afternoon.

It is a major step forward towards reducing the size of the Lords which is one of the biggest legislative chambers in the world.

Earlier this month the House of Lords voted in favour of a motion, proposed by Lord Cormack, that its size should be reduced, and methods should be explored by which this could be achieved.
