Thousands of revellers have turned out to celebrate St Patrick's Day in London.
A parade including marching bands, dancers and a giant model of the Irish patron saint wove its way from Hyde Park to Trafalgar Square on Sunday.
Organisers had expected more than 50,000 people would turn the centre of the city all shades of green ahead of the Irish national day on March 17.

He added: "We help build this great city. We help contribute to this great city and I'm so proud of the links between London and Ireland, between Ireland and Britain.
"Today is an opportunity to celebrate - to celebrate our values, celebrate our connectivity and to celebrate our connection."
Men dressed as giant leprechauns handed out bags of Tayto crisps to children as they watched the bagpipes, drumming, dancing and songs during the colourful parade which included dignitaries and grassroots organisations from the Irish community, including Travellers.

"I always feel welcome, friendly, just happy. I just love the atmosphere - and I have always been into things with leprechauns on even when I was a kid."
