The Queen will celebrate the second day of her Platinum Jubilee today, with the highlight a service of thanksgiving at St Paul's Cathedral attended by senior royals and politicians.
The 96-year-old monarch pulled out of the service last night due to ongoing mobility issues, experiencing "some discomfort" during Thursday's Trooping the Colour and Royal Air Force flypast.
Officials said the journey from Windsor Castle, where she spends most of her time, to London and the activity involved for the service was too much and a regrettable but sensible decision had been taken.
