A petition calling for Republican presidential hopeful Donald Trump to be barred from entering the UK has gathered more than 250,000 names, so MPs will have to consider debating it.
The petition went on Parliament’s e-petition website on Tuesday.
It was posted in response to Mr Trump’s call for a temporary halt on Muslims entering the United States.
Chancellor George Osborne criticised Mr Trump’s comments but rejected calls for him to be banned from the UK.
Any petition with more than 100,000 signatures is automatically considered for debate in Parliament.
Mr Trump is seeking the Republican nomination for next year’s US presidential election.
He said on Wednesday he would never leave the 2016 race, despite the volume of calls for him to step aside.
Home Secretary Theresa May can exclude an individual if she considers their presence is “not conducive to the public good or if their exclusion is justified on public policy grounds”.
Mr Osborne told the Commons that the remarks by Mr Trump flew in the face of America’s founding principles and “were not welcome”.
Downing Street said it was not aware of any plans for the billionaire businessman to visit, so any question of a ban on him coming to Britain was “hypothetical”.
The full text of the petition – entitled “Block Donald J Trump from UK entry” – reads: “The UK has banned entry to many individuals for hate speech. The same principles should apply to everyone who wishes to enter the UK.
“If the United Kingdom is to continue applying the ‘unacceptable behaviour’ criteria to those who wish to enter its borders, it must be fairly applied to the rich as well as poor, and the weak as well as powerful.”
In the US, the Pentagon has warned that Mr Trump’s rhetoric on Muslims undermines US national security by boosting the Islamic State (IS) group.
On Tuesday, US Secretary of State John Kerry added to the widespread condemnation of Mr Trump’s comments, saying they were “not constructive” in the fight against IS.
Mr Trump called for the ban on Muslims entering the United States following a mass shooting in San Bernadino, California.
A Muslim couple, believed to have been radicalised, killed 14 people at a health centre.
The prime minister’s official spokeswoman has said David Cameron “completely disagrees with Donald Trump”.
Labour’s Tulip Siddiq, MP for Hampstead and Kilburn, also called for Mr Trump to be banned from the UK after he claimed that parts of London were “so radicalised” that police were “afraid for their own lives”.
Mr Trump’s comments about the UK capital previously led to London Mayor Boris Johnson saying “the only reason I wouldn’t go to some parts of New York is the real risk of meeting Donald Trump”.
He added: “Donald Trump’s ill-informed comments are complete and utter nonsense.
“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.
