There is a "1,000% mark-up on popcorn" sold in some British cinemas, with customers threatened with removal if they bring in their own food, according to Respect MP George Galloway.
He has put down an Early Day Motion in Parliament, also backed by Conservative MP Sir Peter Bottomley, calling for action on the price of food and drink for cinema-goers.
The Daily Politics tested Labour MP Jim Murphy and Liberal Democrat MP Steve Webb on the cost of cinema snacks after they watched a Daily Politics 'trailer' on the issue.
