What is a party of crows called?

Many wondered how Lansbury's leadership could survive, even though he retained an immense personal popularity. At the Conference this was publicly displayed by delegates, but then during a debate on foreign policy Ernest Bevin launched a withering attack on Lansbury. Heavily defeated in the vote, Lansbury determined to resign as leader. At a meeting of Labour MPs called shortly afterwards there was a great reluctance to accept his resignation, partially out of continued support but also because many Labour MPs feared that the next leader would be Arthur Greenwood, widely seen as heavily aligned to trade unionists like Bevin. In a vote the MPs voted by 38:7 to not accept Lansbury's resignation, but he insisted on stepping down. When it came to selecting a successor (initially envisaged as a temporary position), Greenwood's name was not considered and the party instead unanimously elected Lansbury's deputy, Clement Attlee.
