Britain's Queen Elizabeth and Prince Philip will vacate Buckingham Palace on Friday night (29.04.11) to make way for the royal wedding guests.

They are very happy to leave the palace and will be staying somewhere else.

The couple's grandson Prince William will wed Kate Middleton in a lavish ceremony with a reception afterwards at the palace and while the queen and Prince Philip will attend the celebrations, they intend to leave for their second home of Windsor Castle to allow the younger guests to continue the celebrations.

A source revealed the 85-year-old monarch trusts her grandson and is not worried about leaving her home in the hands of the younger royals.

The insider told Scotland's Daily Record newspaper: "They are very happy to leave the palace and will be staying somewhere else."

The reception - hosted by Queen Elizabeth - for 650 of the ceremony's 1,900 guests will be held in Buckingham Palace's 19 state rooms, where guests are set to enjoy a three-course meal.

In the evening William's father Prince Charles will host an intimate party for 300 family members and close friends of the couple.
