Tennis fans are set to enjoy more beautiful weather at Wimbledon, after thousands watched Andy Murray claim victory in glorious sunshine.
Despite a grey sky, there hasn't been any need for wellies at Glasto yet - yet - with no rain falling at the site so far.
However, more widespread showers are expected by Thursday, just in time for the traditionally-wet festival to kick off in Pilton, Somerset.

Other acts scheduled to play to over 200,000 punters over the weekend include Robert Plant, Haim, Goldfrapp, London Grammar, Ellie Goulding, Metallica, Lana Del Ray, Ed Sheeran and country music legend Dolly Parton.
