Dozens of hereditary peers are set to lose their seats in the House of Lords, after the passage of a bill that will end a parliamentary role dating back hundreds of years.
Peers passed the House of Lords (Hereditary Peers) Bill after ministers offered a compromise to end a long-running dispute with opponents of the reform.
The majority of hereditary peers, who inherit their titles through their families, were abolished in 1999 under the last Labour government and this bill gets rid of the last remaining 92.
Lords Leader Baroness Smith said the "historic legislation" realised Labour's manifesto pledge to remove the right of all hereditary peers to sit and vote in the upper house. "This has never been about the contribution of individuals but the underlying principle that was agreed by Parliament over 25 years ago that no-one should sit in our Parliament by way of an inherited title," Baroness Smith said.
Baroness Smith confirmed the government would offer life peerages to the Conservatives and crossbenchers, meaning some hereditaries are likely to remain in the Lords.
The BBC understands ministers have offered the Conservatives the chance to retain 15 hereditary members of the House of Lords as life peers.
A Lords source said the agreement involves the Conservatives delivering a number of retirements from among their life peers.
The final number of life peerages offered to the Conservatives or any other parties will be decided and announced by the prime minister.
Up to 92 hereditary peers will leave the Lords when the current session of Parliament ends, which is expected to be in May.
The Conservative leader in the Lords, Lord True, said he accepted the government's mandate to end hereditary membership of the upper house. Confirming the Tories would no longer fight the bill, he said he had always believed there was a need to dial down "eternal [parliamentary] ping-pong" even though the compromise would be a bitter pill for some on his side to swallow. In another compromise, the government also plans to increase the number of paid ministers in the Lords - some have worked without a salary due to restrictions in the current law.
Baroness Smith said interim measures had been in place for 25 years since the first hereditaries were removed under former Prime Minister Tony Blair's government.
For hundreds of years, hereditary peers had the right to make and debate laws in Parliament, a right they generally inherited from their fathers and passed on to their sons.
Throughout history most hereditary peers have been male, although some titles have been passed to women including the Countess of Mar who retired in 2020.
In 1999, Blair described their presence in the House of Lords as an "anachronism" and got rid of more than 600 of them but, following what was supposed to be a temporary compromise, 92 were saved.
He said his family had been in the Lords for 900 years - and complained the notice period was less than required in employment law.
"I think this House, Parliament, and the public more widely will miss us," the Earl of Devon said.
He said hereditary peers should be "proud to sit here as embodiments of the hereditary principle dating back a millennium".
He added: "I will miss this place and would of course love to return, but only on merit and not by dint of my hereditary privilege. "
"Whatever views people may have of this constitutional change, it is sad to say goodbye to friends, who in many cases have contributed significantly to debate and scrutiny and to our institutional memory," Lord Forsyth of Drumlean said
