It's been an interesting day of political developments. Here's a quick recap of what's happened.

- David Cameron said he was "hopeful" of reaching a deal with European leaders in February that will then allow him to hold the UK's EU referendum

- When asked whether he would stay on as PM if he ended up on the losing side of the EU vote, he said: "The answer to that question is yes"

- Mr Cameron also declined to guarantee that there would be a net increase in social homes under his plans to demolish and rebuild some housing estates

- Meanwhile, Tory MP David Davis told BBC's 5 live Mr Cameron's lack of a plan for a Brexit was "astonishing"

- And Lord Falconer said the Labour Party needs a "period of calm" in the wake of resignations during Jeremy Corbyn's cabinet reshuffle
