In British sports, a supporters' trust is a formal, democratic and not-for-profit organisation of fans who attempt to strengthen the influence of supporters over the running of the club they support. There are over 140 supporters' trusts across England, Wales and Scotland and the majority of these are affiliated to football clubs, however trusts also exist for Rugby League and Rugby Union clubs.
With government and with cross-party support, Supporters Direct was established to encourage the formation of supporters' trusts to promote democratic supporter ownership. Supporters Direct encourages these bodies to be formed as Industrial and Provident Societies (IPSs) and assists with their formation, legal and start-up costs.
Supporters' trusts were commonly founded in response to a financial crisis which threatens the future of a team, as was the case at Chesterfield, Lincoln City York City, and Real Oviedo. Their involvement has reportedly ensured the survival of over 20 different clubs entering into administration, particularly during the period of crisis as a result of the collapse of ITV Digital. Supporters' trusts are now more commonly founded in order to increase influence at clubs through a financial stake in the club.
The first trust established was at Northampton Town in January 1992. The largest is the Manchester United Supporters Trust, which used to be known as Shareholders United and currently has over 200,000 members. Other large trusts such as Leeds, Exeter City, Dundee United, Reading, Spurs and Glasgow Rangers have between 3,000 and 7,000 members.
