The fourth day of the Diamond Jubilee celebrations saw the Queen honoured at a host of events, despite the notable absence of Prince Philip by her side.

The Duke of Edinburgh was admitted to hospital suffering from a bladder infection but the show went on for the rest of the royals.

The day kicked off with a service of thanksgiving at St Paul's, followed by a lunch at Westminster Palace, a carriage procession and then concluded with a royal balcony appearance, a flypast and a rifle salute.

Here's a look at the best pictures of the day:
