London Mayor slammed after he calls Obama 'part-Kenyan'

London Mayor Boris Johnson has landed himself in hot water after an opinion piece published Friday included claims that the U.S. President Barack Obama dislikes Britain because of his ancestry.

Obama - who has traveled to the U.K. this week - has been accused of arriving in the country at a politically sensitive time with a referendum on the U.K.'s membership of the European Union due on June 23.

In an article written by Johnson in British tabloid The Sun, Johnson claims that the U.K. and America could be "better friends" if the country voted to leave the EU. However, it's a short diversion concerning a bust of Winston Churchill that was focus for a backlash by many readers and political pundits.

"Something mysterious happened when Barack Obama entered the Oval Office in 2009. Something vanished from that room, and no one could quite explain why," the op-ed said.

"On day one of the Obama administration it (the bust) was returned, without ceremony, to the British embassy in Washington. No one was sure whether the President had himself been involved in the decision," it added.

"Some said it was a snub to Britain. Some said it was a symbol of the part-Kenyan President's ancestral dislike of the British empire – of which Churchill had been such a fervent defender."

Although Johnson - who is backing a vote to leave the U - explained that "others" has made generalizations about the U.S. president, one political pundit in the U.K. accused him of "grotesque innuendo." Others simply said that the mere mention of his ancestry showed a lack of respect and dignity.

The social media site Twitter clogged with angry comments referencing the London Mayor's claims and many were quick to point out that the story regarding the bust of Winston Churchill was actually untrue.

An official blogpost by the White House in 2012 confirmed that the present has a prominent place in the President's residence, outside the Treaty Room and was never sent back to the British Embassy.
