Khan told BBC Radio Friday, "The idea that you can blame (a rise in crime) on immigration from Africa is I think preposterous and we should call him out when he does so".
Trump said he had made a suggestion to May on a negotiating tactic with Brussels that she had not taken because it was "maybe too brutal", but she could still use it if things took a turn for the worse.
