Chuka Umunna MP on Leaving Labour, a New Centrist Party and a Second Brexit Referendum

Chuka Umunna is one of the leading members of the new Independent Group - one of now 11 MPs to leave the traditional parties to forge what they call a new centre ground in politics. He talks to Krishnan about what motivated him to take the leap, what an alternative to left/right politics might look like and why he thinks Britain should stay in the EU.
