More than 1.7 million Brits have signed a petition to block Mr Trump’s visit in response to his ban on immigration from seven Muslim-majority countries.
The petition argues: “Donald Trump should be allowed to enter the UK in his capacity as head of the US Government, but he should not be invited to make an official state visit because it would cause embarrassment to Her Majesty the Queen.”
Theresa May has insisted that the visit will go ahead as planned, despite protests from politicians including Labour leader Jeremy Corbyn, London Mayor Sadiq Khan and Scottish Consrvative leader Ruth Davidson.
Parliament will debate the petition on February 20, even though the latest YouGov poll has found that 49 per cent of Brits believe that the state visit should go ahead.
More than 110 MPs signed a motion to stop Mr Trump from being allowed to address parliament if the visit goes ahead.

When is Donald Trump’s UK state visit?
The President will visit the UK “later this year”, according to a Downing Street spokesman.

What is a state visit?
A state visit is the formal visit of a foreign world leader or monarch at the invitation of the Queen. The grand occasion strengthens diplomatic relations.
Previously the Queen has welcomed politicians such as former US President Barack Obama, China’s President Xi Jinping and Mexico’s President Enrique Pena Nieto.
She has also hosted divisive politicians such as Robert Mugabe in 1994 and Vladimir Putin in 2003.
