Umunna: Boris didn't say anything to reassure Remain voters

Chuka Umunna MP gives his reaction to Boris Johnson's Brexit speech at Policy Exchange on Wednesday. The Labour MP for Streatham said that the Foreign Secretary would never be able to unify the UK because of the "lies" he told about extra money for the NHS. Mr Umunna also highlighted Mr Johnson's failure to explain why Britain should jeopardise the Good Friday Agreement by leaving the Customs Union .
