One of the architects of Brexit has been told he cannot enter the US to attend his own inauguration party, it has been reported.

Arron Banks, the British businessman who put millions of pounds behind a campaign for the UK to leave the European Union, was due to travel to Washington DC this week for the party before his entry was blocked.

He has branded the rejection of his electronic entry permit, or ESTA, a “political decision” made by President Joe Biden’s administration.

The party, said to have cost £150,000 to organise, was due to go ahead without him in the US capital on Friday night as a celebration of Donald Trump’s inauguration, set to take place the following Monday.

Three hundred guests have been invited, including president-elect Donald Trump, X boss Elon Musk and former prime minister Liz Truss.
