Members of the Royal Family were spotted filing into the Cathedral ahead of the Service of Thanksgiving.
Service of Thanksgiving for the Queen's Platinum Jubilee took place at St Paul's Cathedral this morning, attracting Royals, politicians and over 400 members of the public.
The Queen pulled out of the thanksgiving service last night, after experiencing "discomfort" at the parade at Buckingham Palace.
The decision was made with "great reluctance" after pondering on the "journey and activity required", the Palace reported.
Among the first members of the Royal Family to arrive were Zara Tindall, the daughter of Princess Anne, accompanied by her husband Mike Tindall.
The Queen's son, Prince Andrew was absent from the ceremony following a positive covid test, but his daughters attended on his behalf.
Prime Minister Boris Johnson attended the event accompanied by his wife Carrie Johnson. They were greeted with boos and jeers upon ascending the stairs of St Paul's Cathedral.
Politicians including Labour leader Sir Keir Starmer and former Prime Minister Theresa May attended the ceremony.
Senior royals and extended members of the Royal Family travelled the short distance from St Paul's to London's Guildhall for a reception which is being hosted by the Lord Mayor of the City of London.
The Duke and Duchess of Sussex will be absent from the Thanksgiving reception, held at the Guildhall.
Guests at the reception include many of those who attended the religious service, including royals and senior politicians.
