The league donates all its profits to charities and good causes and has received praise from Gordon Brown, David Cameron, Prince Charles and Boris Johnson for its community efforts.
The induction evenings will take place at Northumberland C of E Academy on Monday over the next few weeks and anyone interested in the free lessons should call 0333 123 2340, email email@example.com or visit www.leisureleagues.net/Become-A-Referee.aspx
Charitable projects for 2017 being supported include the Dogs Trust, Cancer Research.
