Former Obama White House staffer Bruce Wolpe says US President Donald Trump has broken with precedent by backing Boris Johnson to become the next prime minister. Mr Trump is in Britain for a three day trip, which coincides with British PM Theresa May's last week in charge. The Conservative Party is in the process of selecting its new leader, with Mr Johnson thought to be the favourite. Mr Wolpe told Sky News that President Trump 'likes to tell Britain what to do' and enjoys 'picking winners' when it comes to politics.
