Protesters pledge more anti-Boris booze-ups

Future venues for mass parties against London Mayor Boris Johnson include Leicester Square and Hyde Park, according to entries on the social networking site Facebook.

Several groups were set up on the website specifically to organise Saturday's protest - including the Anti-Boris Tube Crawl, One Final Tube Booze Party, the Circle Line Cocktail Party and the Last Round On The Underground.

One Facebook group - London Underground's Last Ever Party - has already begun the discussion for the next demonstration. Its organiser Ryan Sampson posted this message yesterday: "After the Carnage! Brothers in arms! Thanks y'all to everyone who came and had a great time last night. We rocked !

"... massive cheers for the fact that there were only a few knobheads making things violent and barely any incidents or arrests as a result. I'd call that a roaring success, what what?!

"But now to the future. Allons-y. What next? A freaky frat party in a Tesco's car park? A motherfunking mash up in Leicester square? let's keep the party happening!"

Another Facebook site - Operation Buck Foris - is also planning a "post protest celebration party" for 14 June in Hyde Park.

Details of some of the organisers behind the Saturday night protests can be revealed today. Alexandre Graham, 26, who set up the Circle Line Party - Last Day Of Drinking On The Tube, which attracted more than 1,000 members on Facebook - is a bilingual graduate in mathematics and management from Loughborough University who has spent the past 18 months working as a banker with the Royal Bank of Scotland.

Mr Graham, 26, who rents a flat in Fulham High Street in west London, said he had "no idea" the Circle Line gathering would spiral so badly out of control.

"I hope I don't get sacked," he said today. "You are going to expect a bit of trouble, but I was surprised and disappointed because I don't want to be associated [with it]."

Referring to his qualifications and position at the RBS, he joked: "It makes me sound like a responsible person and not a lunatic - but I am one."

Mr Graham said the idea for the party came from a dislike of new London Mayor Boris Johnson - but admitted it was also about getting drunk. He said: "One of my friends worked for Ken in the environment department but was sacked after he left - it's any excuse to get at Boris."

Mr Graham's co-organiser Ian Rawlings, 23, an exhibitions executive who lives with his parents in Saffron Walden, said: "We all have very good jobs, we work hard for our money and when we get the chance to spend it we like to spend it."

However Mr Rawlings, added: "While we wanted to enjoy ourselves and have a bit of fun, and almost stick two fingers up at the establishment, we also know it is not just our Tube. Other people have to use it."

Another group, One Final Tube Booze Party, which attracted more than 4,000 members, was set up by student Dan Collings, 19. Mr Collings, a graphic design student at London Metropolitan University who lives in Stepney Green, said: "Our group was all about fun, not vandalism, getting on well with police, carrying our litter off the trains. It's a shame that other groups were not so well-behaved, as members of the public got intoxicated and ended up getting themselves arrested.

"Other people took it too far, and started vandalising carriages on other trains - which I find stupid, because it's more evidence that drinking should not be allowed on the Tube."

Witnesses described nightmarish scenes on trains and in stations as drunken people fought and vomited.
