The only catch is that they have to bring an orange and show a team member at the bar to claim their reward: either a 25ml measure of Beefeater Blood Orange or Pink Strawberry gin, served with a Schweppes tonic.

A spokesman for Greene King said: "Everyone loves a freebie and World Gin Day is the perfect time to treat our locals with a refreshing summer drink.

“Our giveaway for World Gin Day is just one of the exciting activities happening at our pub this summer for Greene King’s Great British Summer Social, which will see more than 1,500 events happening at pubs nationwide.

“We can’t wait to welcome our locals in for a free G&T this weekend and to experience the events at our pub throughout our Great British Summer Social – let the celebrations ‘be-gin’!”
