Two peers have been suspended from the Labour Party over claims they offered to carry out parliamentary work in return for cash.
Ex-cabinet minister Lord Cunningham and former senior police officer Lord Mackenzie of Framwellgate were recorded by undercover Sunday Times reporters posing as lobbyists.
In a statement, the party said the pair “have been suspended from the Labour Party pending further investigation.
“The Labour Party expects the highest standards of its representatives and believes that they have a duty to be transparent and accountable at all times.”
Lord Laird earlier resigned the Ulster Unionist party whip after being targeted by the same investigation.
All three deny breaching the rules and have referred themselves to the House of Lords Commissioner for Standards.
The three peers are alleged to have told reporters posing as lobbyists representing a fake solar energy firm they could help push its agenda in apparent breach of a ban on paid advocacy.
It comes just two days after MP Patrick Mercer quit.
