Jeremy Corbyn has officially launched Labour's election campaign with a promise that his party would change Britain from a rigged system for the rich, to a country where people can lead richer lives.

So where does Labour support currently lie, and who might the party need to appeal to if it wants to get more votes?

Jane Green is a professor of political science and works on the British Election Study. She told Radio 4's World at One, that current support is coming from people who "are significantly more left wing than those who voted for them in 2015".
