The Queen arrived for the Jubilee thanksgiving service looking elegant in a fine silk tulle and mint green chiffon drape – and the wives of the political leaders in attendance also wore eye-catching outfits.
Samantha Cameron wore a rose-print Paul Smith outfit and a natty grey beret.
A smiling Justine Thornton, wife of Labour Leader Ed Miliband, plumped for a blue and white ensemble with matching hat.

Foreign Secretary William Hague's partner Ffion kept the colours low-key, along with Chancellor Osborne’s wife Frances.
However, Miriam Gonzales, wife of Nick Clegg, London Mayor Boris Johnson’s wife Marina, and former Prime Minister Sir John Major's wife Norma all opted for bright hues.

The Queen, accompanied by her lady-in-waiting, Diana Marion, The Lady Farnham, twice waved to the crowd as she walked up the steps.
The service at St Paul's Cathedral featured a sermon by The Archbishop of Canterbury, Dr Rowan Williams, and a speech by David Cameron.

After the service, the waiting crowd gave the Queen a huge cheer as she left, with the bells chiming in the background.
Much to the crowd’s delight, she paused on the steps again to give a quick wave, before being driven away.
