Celebrations for St Patrick's Day took place in central London on 13 March, with organisers saying more than 100,000 people were due to take part. The event brought the best of Irish culture and a packed programme of entertainment to the city's Trafalgar Square.
A colourful parade left Piccadilly at noon and wound its way to Trafalgar Square, featuring a showcase of London Irish sports clubs, dance schools, marching bands, community organisations and pageantry.
"Today is a huge party for London and it's huge party for the Irish in London. We are going to have over 100,000 people here today to celebrate Irish community and culture. The sunshine helps so we are shaping up for a great day," said organiser Gary Dunne.
Although St Patrick's Day falls on 17 March, London has maintained the tradition of celebrating on weekends around that date.
