MPs are to consider calls to remove Church of England bishops from the House of Lords and introduce a compulsory retirement age for their peers.

Former Conservative minister Sir Gavin Williamson tabled amendments in a bid to pressure Labor to deliver on manifesto commitments and then go further in the party’s efforts to reform the upper house.

The House of Lords (hereditary peers) Bill seeks to fulfill Labor’s pledge to bring about “immediate modernization” by abolishing the 92 seats reserved for birthright peers.

Labour’s manifesto also said it would eventually impose a retirement age of 80 on members of the Lords.

The government has yet to set a timetable for further changes, including its long-term ambition for an “alternative second chamber more representative of regions and nations”.

Sir Gavin, MP for Stone, Great Wyrley and Penkridge, tabled a series of amendments which will be heard at the bill’s committee stage on Tuesday.

The first clause would prevent bishops of the Church of England from being members of the Lords.

New clause three would ensure that peers would no longer be entitled to be members of the Lords at the end of the parliamentary session in which they reach 80 and that no one would be able to be made a peer for life after reaching that age .

New clause four aims to introduce a minimum participation requirement for peers of one contribution every eight sitting weeks, while new clause five would result in consultation on proposals for an alternative second chamber.

Sir Gavin tabled further amendments, including one to establish a commission to advise the Prime Minister on who should be recommended for appointment as a non-party political peer.

Speaking at the second reading of the bill, Sir Gavin said it was “fundamentally wrong” that his children, who are Catholic, had “no form of representation” in the Lords.

He said last month: “There is a big opportunity here. There is an injustice, there is an injustice that so many people of so many faiths, and so many people with no faith at all, see that there are 26 bishops (in the House of Lords).

“They don’t reflect the UK or what this country looks like today and yet they are still there.

“I will therefore, if the Government are not prepared to table an amendment, table an amendment to remove these 26 bishops from (the House of Lords).”

Other MPs have also put forward proposals, including the SNP’s Pete Wishart (Perth and Kinross-shire), a long-standing critic of the House of Lords, proposing the abolition of the upper house.

The bill is expected to be approved by the Commons on Tuesday after completing its committee stage and third reading.

It will next face further scrutiny in the Lords, where it could face tougher resistance.
