Prince Philip and Queen Elizabeth bid farewell to outgoing Prime Minister Theresa May at Buckingham Palace. They also welcomed the incoming PM Boris Johnson who arrived at the Palace on the invitation of the monarch.

Prince Philip rarely attends state events these days after he retired from royal duties in 2017. He will, however, make an exception for the event to join his wife. PM Theresa May will formally tender her resignation in the presence of the Queen. The new PM will assume the office after her resignation. Boris was invited by the monarch to the palace to form a new government.

Since he retired from royal life, the 98-year-old Prince now spends most of his time on the royals Sandringham Estate in Norfolk. The Duke has stayed by Her Majesty's side and supported her throughout her reign. The Queen considered her husband her "strength and stay."

The Duke enjoyed walking in the country and painting watercolors when he retired. He is now back at the Buckingham Palace to witness the latest change in British Prime Ministers. The Duke stayed by his wife's side when Theresa May renders her resignation and when Boris Johnson presents himself as the new PM.

Queen Elizabeth had to delay her summer trip to Balmoral for a week to witness Boris rising to power. The couple will proceed to Scotland after the Queen has fulfilled her royal duty on that day.

Theresa May was accompanied by her husband Philip when she met the Queen in the Buckingham Palace. The outgoing PM needs to resign to the monarch before the Queen could give a mandate to her successor.

After the meeting, the Queen released a statement saying that the Right Honourable Theresa May MP had an audience of The Queen this afternoon and tendered her resignation as Prime Minister and First Lord of the Treasury, which Her Majesty was graciously pleased to accept.

Boris will serve as the new leader of the Conservative Party. He won the Tony leadership award race with 66 percent of the votes. He arrived at the Palace to meet the Queen shortly after Mrs. May left.

He was welcomed by climate change protesters who blocked him from driving down The Mall to Buckingham Palace. The protesters wore red t-shirts, and they tried to create a human chain across the road. The police escort quickly broke them of the incoming PM.
