Sales of Brockmans Gin fizzed up 90% while revenue climbed 35% to £4.73m over the year, as bottles of the premium spirit were sold at Booths and Asda supermarkets for the first time.

The company said it sold enough to make 14million G&Ts in the period.

It started selling in more than 400 Asda stores and all 28 branches of Booths.

Since then it has also gone on sale in 250 Morrisons stores.
