Rangers chairman Sir David Murray says the club will impose lifetime banning orders on any supporters convicted of taking part in the violence which occurred in Manchester on Wednesday night.

A "small minority" of the 150,000 people who travelled to the city to watch Rangers play against Zenit St Petersburg in the Uefa Cup final clashed with police after a screen which was due to broadcast the game broke down.

An inquiry has been launched by Manchester City Council and yesterday Steven Purcell, leader of Glasgow City Council, wrote an open letter to the people of Manchester admitting he was "ashamed" of some of the behaviour reported.

As a result of Wednesday night's trouble, a homecoming parade through the city by Manchester United, should they win the European Cup, has been abandoned. The decision was made yesterday by the city council, criticised for its handling of the Uefa Cup final, along with Trafford Council, Manchester United and Greater Manchester Police.

A joint statement said: "There will not be a parade immediately following the Champions League final next week but details are being discussed to organise an event which may take place during the summer."

Some 15 police officers suffered minor injuries in the street riots and a Russian fan was stabbed at the City of Manchester Stadium.

One police officer, who was seen in CCTV footage being kicked and stamped on by a group of fans, said it was the worst violence he had witnessed in a match in his 23-year career.

The Rangers chairman said: "We deplore the actions of a small minority who were involved in the disturbances and support the severest action taken against them. The club can confirm that we are already taking steps to deal with the people who have appeared in court and have been convicted of involvement in the disturbances on Wednesday and they can consider themselves banned from any further recognised involvement with the club."

In an open letter published in a newspaper in Manchester, Mr Purcell, who was at the game, condemned the scenes of drunkenness and violence. "They are not acceptable in Glasgow and they are not acceptable in Manchester," he said. "I, as a Glaswegian, am ashamed of the behaviour of some people on Wednesday night and I know there are many other Glaswegians who feel the same way.

"Manchester is not to blame for what happened, Rangers Football Club is not to blame for what happened, the vast majority of Rangers supporters are not to blame for what happened. The only people to blame are the mindless minority who acted in the irresponsible, idiotic and violent ways we have all witnessed."
