Theresa May is due to speak to Donald Trump after the Government confirmed he will be given the "full courtesy" of a state visit despite the heavy opposition to it.
The Prime Minister is expected to speak to the President over the phone around 4:30pm GMT today, following the Foreign Office's rejection of a petition to downgrade Mr. Trump's visit.
The petition had called for the Government to downgrade the trip from a formal state visit and instead extend Mr Trump the courtesy of a regular foreign diplomat visiting the United Kingdom.
Because it had garnered over 10,000 signatures, the Government had to reply to it, with support for the petition growing after the executive order to ban travel to the US from seven majority-Muslim countries was imposed.
In a statement on their ruling, the Foreign Office said: "HM Government believes the President of the United States should be extended the full courtesy of a state visit.
"HM Government recognises the strong views expressed by this petition, but does not support it.
"This invitation [extended by Theresa May while visiting Washington] reflects the importance of the relationship between the United States of America and the United Kingdom.
"We look forward to welcoming President Trump once dates and arrangements are finalised."
The news comes after President Trump faced more unwelcome headlines, following the resignation of his national security advisor, Michael Flynn.
