The Queen has promised to "rededicate myself to the service" of the UK and its people during an address in Westminster Hall to both Houses of Parliament as part of her Diamond Jubilee celebrations.
In a speech on 20 March 2012 she said the commemoration of her 60 years on the throne was a chance "to come together in a spirit of neighbourliness and celebration".
A stained glassed window commissioned for the Jubilee was unveiled.
Hundreds of dignitaries, including Prime Minister David Cameron, his deputy Nick Clegg, Labour leader Ed Miliband and Archbishop of Canterbury Dr Rowan Williams, assembled for the speech, which was greeted with a standing ovation.
The Queen responded to tributes made to her by
earlier this month.
Before the Queen addressed the assembled politicians, speeches were made by the Lord Speaker, Baroness D'Souza, and the Speaker of the Commons, John Bercow MP.
