Future Orange Order marches in Glasgow could be banned in light of footage showing members of the public chanting a sectarian song.

Council officials have warned future parades face greater restrictions or even prohibition after police launched an investigation into the incident.

Footage emerged online of people singing the anti-Irish Famine Song, while a band played along, during what appears to be the annual celebration on Saturday.

A spokesman for Glasgow City Council said: "The European Convention on Human Rights enshrines the rights to peaceful assembly and freedom of expression.

"However, these rights are not absolute. They must be balanced by the responsibility to ensure the rights of others are not infringed.

"As with all public processions, there will be a debrief involving Police Scotland, the organiser and the council."

He added: "The council will take into account any issues of public disorder, antisocial behaviour or damage to property resulting from the procession.

"It will also take into consideration any evidenced issues and, if a future procession notification is received from the organiser, the likelihood of any restriction or prohibition may be greater."

The song, sung to the tune of the Beach Boys' Sloop John B, has previously been ruled to be racist by a Scottish court.

David Scott, campaign director for anti-sectarian group Nil by Mouth, said: "If they [the Orange Order] are a religious and cultural organisation, what would be the relevance of a Beach Boys song?

"We know that tune also has another certain set of lyrics. The organisers should be speaking to band members and saying what is acceptable."

The main County Grand Orange Order parade from George Square to Glasgow Green featured 4500 people in 63 bands taking part, with another 4000 spectators.

Eight arrests were made for alleged minor disorder and alcohol-related offences.

Robert McLean, executive officer for the Grand Orange Lodge of Scotland, said: "At the end of the day, members of the public will sing songs to tunes.

"I have been quite clear - if police investigate we will assist with their enquiries. We look forward to the debrief and looking at any incidents that occurred."

A police probe was launched after the footage emerged online.

Chief superintendent Brian McInulty said: "Saturday's policing operation primarily focused on the safety of the public during the parades.

"Police Scotland, however, operates a zero-tolerance policy when it comes to any form of sectarian abuse and will fully investigate any incidents brought to their attention."
