A petition calling for Republican presidential hopeful Donald Trump to be barred from entering the UK has gathered more than 300,000 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.
There's way more pressing issues that could use those signatures and be debated in parliament. Instead people are wasting their time trying to get this celebrity banned which won't happen.
