Twenty-six MPs have registered their support for the MA's campaign against blanket glass bans.
They signed the early day motion (EDM), submitted by Selby MP John Grogan and drafted by the MA, opposing police moves to force all venues to go glass-free.
Meanwhile, the MA's on-line petition to Prime Minister Tony Blair, opposing blanket glass bans, has gained almost 2,000 signatures.

MPs from the three main political parties have added their name to EDM number 1508.
This includes Labour MP Andrew Dismore - joint-chairman of the All-Party Parliamentary Wine and Spirit Group - and Nigel Evans, Conservative MP for Ribble Valley and president of National Pubwatch.
The EDM says: "This House supports the replacement of glass with polycarbonate (plastic) vessels in specific licensed premises in order to combat crime and disorder; accepts that on occasions licensing committees will have to order such premises with a poor record to make such a switch, but believes that blanket, indiscriminate and widespread bans on ordinary glasses across whole areas would be a disproportionate response which would diminish the pub-going experience and undermine the proper enjoyment of hospitality for citizens and tourists alike; notes the unacceptable environmental impact of a widespread switch to plastic, which cannot be recycled as easily as glass; and in line with the campaigns being led by the Morning Advertiser and the Bar Entertainment and Dance Association calls on licensing authorities and the police to seek to impose such conditions only where absolutely necessary as prescribed by the Licensing Act 2003."
