One of the world's largest music festivals starts today and it's a complete mud bath

Glastonbury Festival, one of the world's biggest music events held every summer in Somerset, is open to the public today (June 22). But heavy rain has filled the venue, Worthy Farm, with pools of mud and waterlogged fields.

Festival-goers who have been to Glastonbury in previous years may be used to the wet weather, yet many people still turn up to the five-day event unprepared. And more than 100,000 people are expected to show up for the mud-packed event, according to the BBC.

As Glastonbury kicks off, we've compiled photos of revellers as they brave the miserable conditions.
