Labour leader Jeremy Corbyn has nominated former Speaker of the House of Commons John Bercow, who was previously a Conservative, to the House of Lords for the dissolution honours list.
Prime Minister Boris Johnson’s spokesperson mentioned that it’s a “break in convention” for a party to nominate a member of the opposing party to the House of Lords.
The prime minister’s official spokesman said it would be a break in convention if reports are true that Labour is preparing to put Bercow’s name forward for the dissolution honours list.
I understand that Bercow could sit as a Crossbencher even if he is nominated by Labour.
However, is it unprecedented for a party to nominate someone from an opposing party to the House of Lords and the peer subsequently sat as a member of that party (i.e. former Conservative MP nominated by Labour and sat as a Labour peer)?
