Currently, Prime Minister May finds herself in a political mess over her mostly incompetent handling of Brexit.

The state visit would be an opportunity to strengthen already close ties in areas such as trade, investment, security and defense, she said. During that meeting, they appeared to keep the Queen waiting - though Donald Trump later claimed that the Queen was the one who kept him waiting - and inspired mass protests across London from Brits who were really not thrilled about the Trumps' visit.
However, it's not yet clear whether the US President will, like most of those invited to make a State Visit, find himself addressing both Houses of Parliament.
On the final day of their visit, Trump and the first lady plan to attend a ceremony in Portsmouth, a naval city on England's south coast, to commemorate the 75th anniversary of the D-Day landings, when Allied forces invaded northern France.
President Trump is yet to tweet about the upcoming trip.
Though many other presidents have visited the monarch, only two - George W. Bush and Barack Obama - were honored with a state visit, which typically features royal pomp including a banquet with the queen at Buckingham Palace.
Trump will also visit Queen Elizabeth II and Prime Minister Theresa May during a visit to the United Kingdom and also recognize D-Day at a ceremony in Portsmouth. Mrs May said she looked forward to the chance for the United Kingdom and USA to strengthen their "already close relationship".
Mrs May said: "The UK and United States have a deep and enduring partnership that is rooted in our common history and shared interests".
The Queen normally only receives one or two heads of state each year.
The Speaker said at the time that addressing Parliament was "not an automatic right, it is an earned honour".
"With Donald Trump coming I think the chances are that it will move from being around commemoration and instead it will be a day of controversy", said councillor Gerald Vernon-Jackson, a member of the opposition Liberal Democrats.
