On 9 March 2011, Cheltenham MP Martin Horwood proposed a bill under the ten minute rule aiming to reform pub contracts, known as "ties", to help struggling landlords.
So-called "beer ties" require tenant landlords to buy beer supplies only from owner firms.
Mr Horwood believes that this allows large pub companies to "impose impossible terms on local tenant landlords", forcing struggling pubs to close.
His Tied Public Houses (Code of Practice) Bill, which has attracted cross-party support, would allow landlords to buy beer from other sources, with the option to become free of the tie.
An investigation by the Office of Fair Trading ruled in October that beer ties were not anti-competitive.
The watchdog said that consumers had a wide choice between pubs and that this competition prevented the beer tie from being used to inflate prices beyond competitive levels.
