The procession began at 10am when Thatcher’s coffin was driven by hearse from the Palace of Westminster.
Big Ben was silenced but the bells of Westminster Abbey rang out.
At 10.30am the hearse reached St Clement Danes where the coffin was transferred to the bottle-green gun carriage drawn by the Kings Troop Royal Horse Artillery.
At just before 11am, Thatcher’s coffin reached the steps of St Paul’s.
An 18-strong guard of honour, made up of forces members and Chelsea Pensioners, saluted as she was carried inside.
She was later cremated in a private ceremony in Mortlake, South West London.
