St Patrick's Day celebrations in central London are returning on Sunday. Organised by the mayor of London and the London Irish Centre, a parade featuring floats, marching bands, dance troupes and pageantry will travel from Hyde Park past Trafalgar Square and on to Whitehall.

Run entirely by volunteers, the New York event was first held in 1762, making it the oldest St. Patrick’s Day parade in the world, according to its website. It’s also the largest, drawing about 150,000 marchers and nearly two million spectators each year, the site says.

The celebration attracts upwards of 80,000 people each year making it one of the largest parades across the country.
