A group of MPs wants the Government to organise a summit at which charities, clothing collection agencies and representatives of various government departments would discuss a clampdown on bogus charity clothing collectors.
The early day motion, which was tabled on Wednesday, says research by collection agency Clothes Aid and the Department for Environment, Food and Rural Affairs showed the problem was costing charities up to £12m a year.
It says trading standards bodies should be given more power to regulate charities and commercial firms that operate textile collections.
An Office of the Third Sector spokeswoman said it was already working on a campaign called Give with Care, designed to raise public awareness of bogus collections.
"Powers to tackle this problem already exist, and where bogus collections break the law we encourage enforcement of the law by the relevant agencies and regulators," she said.
She said the OTS was happy to discuss the issue with any concerned parties.
