Chuka Umunna

With Brexit the main preoccupation for politicians in Britain, the opposition Labour Party has announced a shift in policy which would see the UK retaining most of the elements of its current relationship with the EU. It wants Britain to have full access to the single market and stay a member of the customs union. But that does not go far enough for some staunchly pro-EU members of the party who want Britain to stay part of the European Economic Area. HARDtalk's Zeinab Badawi speaks to Labour MP and prominent EU campaigner Chuka Umunna about challenging the Conservative government and his own Labour Party leadership on Brexit.
