The National Trust is among a number of charities warning Sir Keir Starmer they face being 'crippled' by new consumer rights rules.
They have expressed fears that recent legislation has created a 'loophole' allowing abuse of their membership schemes.
In a letter to the Prime Minister, the charities outlined how provisions under the Digital Markets, Competition and Consumers Act might see them lose out on critical funding.
Under the legislation, Britons are entitled to cancel a subscription contract during a two–week 'cooling–off' period.
The Act is intended to crackdown on 'subscription traps' where consumers are misled into signing up for a subscription through a 'free trial' or reduced price offer.
