Corbyn appointed John McDonnell as Shadow Chancellor and promoted several female backbenchers, forming a Shadow Cabinet that for the first time had more women than men. Under Corbyn's leadership, Labour shifted to the left from the centre-ground. In November 2015, he voted against British military involvement in the Syrian Civil War. He also opposed the renewal of the Trident nuclear weapons system and apologised for the Blair ministry taking the UK into the Iraq War. In spite of his victory, Corbyn enjoyed little support from Labour MPs, although his support remained strong amongst Labour Party members. In 2016, Labour performed poorly at the local and regional elections, and following the European Union membership referendum, in which Britain voted to leave the EU, party opponents accused Corbyn of running a lukewarm campaign for Remain. Several resigned from the Shadow Cabinet and Corbyn lost a motion of no confidence by 197–40. Angela Eagle and Owen Smith launched a formal challenge, although Eagle later withdrew. Corbyn was re-elected with a marginally higher majority of 61%.
