Queen Elizabeth II will address both Houses of Parliament to mark her 60 years on the throne.
The Queen's visit to Westminster Hall will begin with the humble address by Baroness D'Souza, from the House of Lords, and House of Commons Speaker John Bercow making a similar speech from the Commons, a Press Association report said.
The Queen will then address dignitaries including Prime Minister David Cameron, deputy prime minister Nick Clegg and other former prime ministers before unveiling the Diamond Jubilee Window commissioned to mark the monarch's 60-year reign.
The window designed and produced by British artist John Reyntiens is made up of 1,500 pieces of glass. The image is inspired by 17th-ccentury heraldic art.
The window will be contained in a display case and installed above the North Door of Westminster Hall.
The Queen gave historic speeches in both Houses in 1977 and in 2002 to mark her silver and golden jubilees. The diamond jubilee celebrations began on 6 February and will extend till June.
