The organiser of a pro-independence march through Glasgow has questioned the 'political bias' of council officials after being asked to attend a hearing about the parade.

Glasgow City Council have raised concerns over impact of the All Under One Banner (AUOB) march on May 4 after emergency services warned the size of the event could have a "detrimental impact on the city centre".

Organisers say they will not change the planned 1pm start time of the procession, despite fears it would cause emergency servies to declare a "major incident" to manage the 100,000-strong crowd expected to turn up.

The group have now blamed political bias for the "eleventh hour" involvement of Glasgow City Council.

Neil Mackay, spokesman for All Under One Banner, said: "There are a number of reasons this has happened.

"The idea there will be pandemonium and hysteria on the streets, that's just not the case. We are very well behaved, and are very organised. We are very happy to work with the council.

"But this is political bias from certain departments at the council, land and environmental services and the processions department. We have always had problems with them.

"There are departments that obstruct All Under One Banner, continued over as dinosaurs from the red Tory, Labour administration in Glasgow City Council. They have a clear agenda to cause disruption.

"We want independence yesterday, so this march is about showing our authority, we won't be shunted around by the council."

Glasgow City Council have refuted suggestions of bias by staff.

They say several factors, including safety issues at previous AUOB events, prompted their request to rearrange the parade.

A council spokeswoman added: “It’s nonsense to suggest that our officers are anything other than professionals and totally dispute this unfounded allegation.

"In this case, a variety of concerns have been raised - including the time of the procession; whether organisers have adequately prepared for the number of people likely to take part, and a series of public safety issues with previous events held be the same group.

"The organiser has refused to negotiate any resolution to these issues and, as such, we have no alternative but to take the matter to committee."
