Traffic wardens should be given extra powers, thus easing the burden on police officers and making the wardens feel more ''worthwhile'', according to a leading Scottish police officer.

The move, suggested by Mr Roy Cameron, the Chief Constable of Lothian and Borders, was unanimously supported by members of the Joint Police Board at a meeting in Edinburgh yesterday.

Mr Cameron is now seeking a meeting with the Secretary of State for Scotland.

Traffic wardens' powers are currently limited to non-endorsable offences such as issuing fixed penalty tickets, said Mr Cameron.

But since the introduction of the bus-priority Greenways system in Edinburgh, which Mr Cameron said had placed increased pressure on the police, there had been moves towards a more flexible use of wardens and a more ''worthwhile'' approach for them.

As well as dealing with Greenways offences, Mr Cameron wants wardens to have extra powers to deal with other traffic offences.
