A cross-party group of peers and MPs have quietly set up a committee to look into reducing the size of the House of Lords – a swollen chamber second in numbers only to China’s National People’s Congress.

Lord Cormack, a member of Edward Heath’s Tory government in the 1970s, will publish a report later this year which could recommend cutting the number of peers or reducing the intake to the chamber every year.

There are currently more than 820 members of the House of Lords, up from 666 in 1999 when most hereditary peers were removed by the House of Lords Act. The number is set to rise again because David Cameron is likely to appoint more Conservative peers this summer to better reflect the make-up of the Commons. The Prime Minister appointed 186 peers in his first term of office, compared with only 34 created by Gordon Brown in the preceding three years.

Lord Cormack has campaigned for reform of the upper chamber for about 14 years, but his new committee is specifically focused on cutting numbers. At present, there is not enough room to seat more than half the peers, which can lead to strict time limits on speeches during popular debates.

The Leader of the House of Lords, Baroness Stowell, has vowed to be “all ears” when the report is published and says she will “listen very carefully to what noble Lords put forward”. It is understood that MPs are also members of the committee, which is thought to comprise around 10 people, as well as Lord Norton. A Tory constitutional expert is also involved.

A source close to the committee said: “It will be addressing the issue of numbers and procedural matters of the House of Lords.”

One MP who is involved added: “Either you’ve got to stop the number of peers coming into the Lords or you’ve got to start getting rid of some who are already there. It’s quite sensitive on how you would do this.”

The MP said there were growing concerns that an unelected chamber was growing, just as the elected Commons is set to shrink from 650 to 600 members in 2020 under a proposal laid out by Mr Cameron.

This has sparked a separate argument over whether the executive also needs to be reduced – there are around 140 ministers and parliamentary private secretaries, most of whom are MPs. Many backbenchers and opposition MPs believe that there needs to be a similar reduction in ministerial positions to ensure their work is properly scrutinised by the remainder of the Commons.

Peter Bone, the rebellious Tory MP for Wellingborough (inset, left), said: “Certainly, if you reduce the number of MPs, then you’re going to need to reduce the size of government. You could get rid of the Department of Energy and Climate Change and put it in Business, Innovation and Skills.

“The Government has got to look seriously at this – the Government payroll is getting huge,” he added.

Peers are also plotting to veto government plans to bring forward changes to the way the electoral roll is collected. In 2013, it was announced that there would be a transition from the head of a household registering voters in their home to individuals doing it themselves, the change to be introduced over a three-year period.

The Government now wants to complete the switch by the end of this year. But the Electoral Commission found that 1.9 million people’s entries are still registered under the transitional arrangements, which means that they might not be eligible to vote in 2016, a year that includes Welsh and Scottish elections.

The Lib Dems have tabled a motion against the move in the Lords and Commons and the Labour and crossbench support should be enough to bring down the plans.
