Brexit is obviously the motivation behind it, getting rid of May and installing a PM who will keep us in the single market is the option left for the establishment remainers. We're days away from the behind the biggest negotiations in our countries recent history and they're calling for May to step down because she didn't virtue signal enough. I'm sorry but being a good people person is not a requirement for PM, it's why I hate TV debates they become all about charisma, body language and other pointless personality traits.
I wouldn't say that those traits are pointless. Part of being a good leader is being able to inspire and connect with others. Unfortunately for May she has come after two Prime Ministers in Blair and Cameron who were very good at it.
