Theresa May has formally rejected a petition signed by 1.8million people calling for a state visit by Donald Trump to be abandoned because it will "embarrass" the Queen.

The Government's response to the petition "recognises the strong views" of those who supported the petition but says he should be extended the "full courtesy of a State visit".

It says: "HM Government believes the President of the United States should be extended the full courtesy of a State Visit. We look forward to welcoming President Trump once dates and arrangements are finalised.
