Boris Johnson was accused of 'dog whistle racism' and likened to right-wing 'Tea Party' politicians in the US this morning after his attack on the 'part-Kenyan' Barack Obama.
The Mayor of London spoke out against the US President after he urged British voters to stay in the EU and mentioned his African ancestry as he criticised the decision to remove a bust of Sir Winston Churchill from the Oval Office shortly after Mr Obama entered the White House.
Mr Johnson - who is favorite to succeed David Cameron as Prime Minister - suggested the President got rid of the statue as a 'snub' to Britain's wartime prime minister and a 'symbol of the part-Kenyan President's ancestral dislike of the British empire'.
But Shadow Chancellor John McDonnell hit out at Mr Johnson and demanded he withdraw the controversial remarks.
