Sectarian behaviour and drunken disorder will be targeted tomorrow as thousands of people take part in the annual Orange Order parade.

Police issued a warning that sectarian behaviour and drinking in public would not be tolerated. Anyone caught taking part in anti-social behaviour risks being fined.

Around 8000 marchers from the city's 182 lodges are expected at the Glasgow parade to commemorate the Battle of the Boyne, with thousands more supporters and followers making for the rally at Kelvingrove Park.

John Neilson, assistant chief constable (territorial policing), said: "While the parade will have a major impact on traffic in the city centre, the main issue for the force and members of the public is the excessive drinking and public nuisance caused by those who follow the parade.

"The force's priority is public safety. We want to make sure people can come into the city centre without too much disruption or feeling intimidated by excessive drunkenness and sectarian or disorderly behaviour.

"By all means follow the march, but note that drinking in public places is not allowed and officers will make full use of anti-social behaviour fixed-penalty tickets to tackle the consumption of alcohol and urinating in public places."

Ian Wilson, grand master of the Orange Order, echoed the police's sentiments.

He said: "The annual Glasgow Boyne Celebrations is the city's biggest street event, and we want spectators to enjoy the music and the pageantry in a carnival atmosphere. We do not wish anyone's enjoyment spoiled by the antics of boozed-up, foul-mouthed followers. There is no place in our celebration for public drinking, abusive behaviour or offensive chants."

Strathclyde Police has been working closely with the Grand Orange Lodge and event organisers to ensure that any disruption on the day is kept to a minimum.

However, drivers are being warned that the march will have a considerable impact on traffic congestion, particularly in Glasgow city centre around George Square, St Vincent Street, Blythswood Square, Bath Street, Sauchiehall Street and Kelvin Way. Officers and stewards will be positioned to assist with traffic restrictions during the parade.

Motorists are advised to follow the advice and directions given and to leave extra time for their journey.

Mr Neilson added: "This is an all-day event and therefore road users, residents, businesses and shoppers can all expect some long delays."
