Banksy reveals he made Stormzy's vest for historic Glastonbury gig

Banksy has revealed he designed the Union Jack vest worn by Stormzy during his historic headline performance at the Glastonbury Festival on Friday night.

The elusive graffiti artist made the revelation in an Instagram post, saying: "I made a customised stab-proof vest and thought - who could possibly wear this? Stormzy at Glastonbury."

The Croydon-born star suggested he had no idea who was behind the black and white design, responding on Twitter by saying he was "absolutely f****** speechless."

Stormzy became the first black British solo artist to headline the famous event in its 49-year history - describing his slot on the Pyramid stage as "the greatest night of my entire life".

At 25-five-years old, he is the second-youngest solo act to headline the festival, after David Bowie in 1971 when he was 24.

Stormzy's show went down a storm, with fellow stars, music fans and MPs praising him for his performance, with Labour leader Jeremy Corbyn describing it as "political" and "iconic".

The grime star saw a gospel choir join him on stage for his song Blinded By Your Grace and thousands of fans joined him when he chanted "f*** the government and f*** Boris".

In response, a member of Boris Johnson's team told Sky News: "I'm glad of Mr Stormzy's support and that he said 'Back Boris' although there was, I believe, an acoustic issue in the venue in which he was performing."

Stormzy used his set - which included a duet with Coldplay frontman Chris Martin - to highlight inequality in the justice system and how ballet shoes were now being made to match black skin tones.

Meanwhile, on the UK's hottest day of the year so far, with temperatures of 33C (91.4F) recorded on Saturday, organisers of the festival insisted they have not run out of water.

The event in Somerset has banned single-use plastic bottles this year because of fears over climate change and some people have tweeted to complain about long queues for taps to refill water bottles.

But in a statement, organisers said: "There is not a water shortage at this year's Glastonbury. Our supply is running as normal.

"As always in hot weather, demand for water has increased, so we have put in place the usual restrictions on staff/guest showers and the limited number of public showers.

"We have more than 850 taps on site, all of which provide free drinking water. These taps all have a ready supply of water."

They said all bars were offering free tap water and that food traders were also selling water and soft drinks in cans.

Organisers said the on-site ambulance control had received 27 heat-related calls for assistance.
