On Monday MPs are holding a debate on whether Mr Trump, the Queens-born billionaire and Republican presidential candidate, should be banned from Britain. A petition to block his entry received over 573,000 signatures – the highest ever number on the parliamentary petitions website – and the Government, in agreeing to the debate, said that the Home Secretary may exclude a non-EU national from the UK “if she considers their presence in the UK to be non-conducive to the public good.”
