"From running successful businesses and supporting public services, to the huge influence on our arts and cultural scene, Irish Londoners are integral to the fabric of our city."
The festivities were first held in Trafalgar Square 20 years ago, with the event being organised by the London Mayor's office.
Chicago River dyed green in annual tradition
Meanwhile in the US, the Chicago River was dyed green yesterday as part of the city's annual tradition marking St Patrick's Day.
Small boats criss-crossed the river and poured gallons of dye into the icy-cold waters.
Spectators gathered along the banks of the river and watched from tour boats as the water gradually turned bright green.
The dyeing of the river, a process that began early in the morning, kicked off a day of festivities, including the city's annual St Patrick's Day parade.
Event organisers say the green hue lasts in the river for several days.
The midwest city has been dyeing its river green since 1962, according to nextcity.org.
