London Mayor Sadiq Khan warns against 'irresponsible hard Brexit'

London Mayor Sadiq Khan has warned the Government that a departure from the single market would be "deeply irresponsible". In a speech to the Confederation of British Industry, Mr Khan urged ministers to be "on the side of business" in Article 50 negotiations and claimed a "hard Brexit" would be the "wrong approach" for the UK. Mr Khan's warning comes as leaked Government papers suggest a departure from the single market would cost the UK up to £66bn in tax revenue
