LONDON — A petition to block Donald Trump from entering the UK has exceeded 275,000 signatures, as British politicians and the public line up to denounce the U.S. Republican presidential candidate following his latest incendiary statement.

Hundreds of thousands of people signed the petition, entitled "Block Donald J Trump from UK entry," after Trump said Muslims should be banned from entering the U.S.

All petitions that pass 100,000 are considered for debate in Parliament, and are "almost always debated." Petitions that reached this stage generally receive a half day of backbench time.

Prime Minister David Cameron dismissed Trump's comments as "divisive, unhelpful and quite simply wrong" while London Mayor Boris Johnson said they were "complete and utter nonsense."

He also laughed off Trump's suggestion that some parts of London are so radicalised that police fear for their lives.

"As a city where more than 300 languages are spoken, London has a proud history of tolerance and diversity and to suggest there are areas where police officers cannot go because of radicalisation is simply ridiculous," he said.

"Crime has been falling steadily both in London and in New York. The only reason I wouldn't go to some parts of New York is the real risk of meeting Donald Trump," he added.

Scottish MP Tasmina Ahmed-Sheikh, meanwhile, said that Trump's comments amount to "hate preaching." The SNP minister said he should be refused entry to the UK.

Author J.K. Rowling has also weighed in, tweeting her dismay at Trump being compared to Harry Potter villain Voldemort. "How horrible," she said. "Voldemort was nowhere near as bad."

According to the heat map on the petition site, a number of the signatories are from the Aberdeen area of Scotland, where Trump has a huge golf course.

Suzanne Kelly, who started the petition in late November before Trump's latest comments, told Mashable she was "delighted" so many people have signed up, saying the support was "beyond my wildest dreams." Long opposed to his rhetoric, she added that her "disgust turned to real worry" when he became a presidential candidate.

Another petition, calling for the TV personality to be stripped of an honorary degree from an Aberdeen university, has also received thousands of signatures.

Overnight, #trumpfacts was trending as much of the UK mocked the candidate's comments on Britain becoming radicalised.
