Scotland's top policeman, Sir Stephen House, is to face opposition from council leaders over the controversial policy of officers carrying guns while on patrol.

A motion opposing the practice that has dogged the national police force for months is to be voted on by local authority leaders after a report presented today.

If passed by the Convention of Scottish Local Authorities (Cosla), the councils' umbrella body, further pressure will be placed on Sir Stephen, the Chief Constable of Police Scotland, to re-examine the policy.

The latest move in the long-running row comes against the backdrop of statements from Sir Stephen and his force that only 10 in every 1,000 officers are armed.

He has also denied that the policy will encourage more criminals to take up arms themselves, pointing out that officers carrying guns leaves communities better protected.

Members of Cosla will examine the report about the use of armed police at a meeting in Edinburgh.

The report invites the leadership to "agree to the principle that police officers should not carry firearms on regular duties ...

"Leaders may want to take a position on the principle of having armed officers on regular police duty, which may contribute to a perception of a heavy-handed approach to policing, when seen alongside, for example, the apparent increased use of stop and search tactics."

All councils accept the need to have an armed response capability. But the presence of armed police officers on Scotland's streets has become a matter of public concern particularly in rural areas, the report says.

Some councillors have spoken out about police appearing at inappropriate venues with sidearms, including shops and charity events.

Some councillors say they do not understand why the w­eapons cannot be kept safe in the boot of armed response vehicles, as was the practice in most areas until the creation of the single force.

The row escalated after officers were seen patrolling with guns in Inverness.

Some councillors do not understand why certain officers must be armed at all times.

The report says: "Failing to respond to local elected representatives' concerns threatens the notion of 'policing by consent'."

Sir Stephen has insisted that the ­decision to have a number of officers permanently armed was an operational matter for him which should not be subject to political interference.

He has pointed out that there are only 275 highly trained specialist armed response officers, fewer than two per cent of the entire police service.

As they work on a shift system, only a very small number of armed officers will be on duty at any one time.

The report suggests a legal opinion might be necessary to examine the parameters of the chief constable's ­operational independence if the d­eployment of armed officers fell outside the remit of operational matters.

The Police Scotland website states: "We have a small number of officers readily armed so the rest of our 17,000 plus officers don't need to be."

It also seeks to respond to concerns that the policy will mean more criminals carrying guns.

It states: "The standing [firearms] authority means our communities are in fact better protected.

"Officers are now able at the start of each shift to attach their weapons so that if an incident does require their support, they are already equipped and not working against time to arm ­themselves in a high-pressure situation.

"This reduces the risk of accidents and keeps themselves, their unarmed colleagues and the public safe."
