Here's a summary of what has been a memorable day in politics. It's been dominated by one man - new Labour leader Jeremy Corbyn, who went head to head for the first time with David Cameron at PMQs.
- Mr Corbyn asked questions emailed to him by members of the public about tax credits, housing and mental health
- Mr Cameron welcomed a focus on "substantial issues"
- The Labour leader tells the BBC's Laura Kuenssberg that he cannot envisage campaigning to leave the EU and also questions whether he should have to join the Privy Council
- The Labour leader has also addressed criticism over his failure to sing the national anthem at a Battle of Britain memorial
- An investigation is under way after a BBC cameraman was injured while filming Mr Corbyn leaving his home.
- In non Corbyn news, official figures show UK average earnings growing at the fastest rate since 2009 while there was a slight rise in unemployment
