A petition to ban Donald Trump from entering the UK has gathered more than 250,000 names.
It was set up after the leading Republican presidential candidate said Muslims should be banned from entering the US, in the wake of the deadly California attacks.
Because more than 100,00 signatures have been added, MPs will now have to consider debating the issue.
BBC News explains what will happen next with the Trump petition.
