Huge parades of Irish brass bands, dance troupes and sculptures marched through towns and villages across the country to celebrate Ireland’s patron saint. The London parade was the largest in the UK with around 50,000 participants.

There were huge queues outside Ireland’s biggest bars with a sea of ​​green waiting to get into London’s Waxy O’Connor’s, which is popular for its live music at the six-story Soho venue .

And there will be a few headaches this morning after consuming millions of pints of Guinness.
