In a speech written by the right-wing Conservative government, Queen Elizabeth II delivered the government's legislative program for the next two years.
However, while King Felipe VI and Queen Letizia of Spain were set to be welcomed to the U.K. in July, there was no mention of Trump. Typically, the State Opening of Parliament includes scheduled state visits.
A spokesperson for British Prime Minister Theresa May said the reason Trump's planned visit had not been detailed in the government's plans was that no date had yet been fixed.
Earlier this month, Trump reportedly called May and said he would not wish to go ahead with the trip if it was likely to spark widespread protests and demonstrations.
May had extended an invitation to her American counterpart in the week following Trump's inauguration in January — during a visit to the White House.
Shortly after the invitation was accepted, thousands of people opposed to Trump's planned trip to Britain protested outside Downing Street while almost 2 million people signed a petition urging May to rescind the invitation.
