The embattled Prime Minister is said to have been urged by the Palace 'do not bring us into it' as the ongoing struggle around his premiership continues. King Charles will deliver the speech, which lays out his government's priorities for the next parliamentary session, tomorrow.

Politico, a news website, reports that people familiar with the matter have made clear to No10 officials how important it is for the King not to be used for political purposes.

"The Palace view is ‘we do not want to be any part of this conversation — do not bring us into it,'" the publication was told.

Sir Keir has faced a nightmare of a week with over eighty of his own MPs demanding he tender his resignation and trigger a leadership election.

They have done so after a disastrous set of local elections which saw more than 1,500 local councillors removed from office, and even led to Labour losing control of Wales for the first time.

The formal opening of parliament will take place tomorrow, and sees the monarch deliver a speech in which he makes clear what his government will do over the duration of the next parliamentary session.

The government was approached for comment by the Daily Express, and did not immediately respond. Neither No10 or the Palace responded to queries made by Politico.

"It is very embarrassing for the king that his government is such a shambles that he has to read out something that may or may not still be the government’s program by the end of the week," a figure familiar with the matter told the publication.

It is understood that the Palace has made clear the King will press ahead with his duties, but it is for parliamentarians to handle the ongoing political crisis and not involve the Monarch.
