THE convener of Holyrood's petitions committee has defended its record following claims it has been short-changing the public.

John Pentland insisted the committee, seen as the main way for members of the public to influence government policy in the Holyrood system, was encouraging people to "engage".

He rejected concerns voiced by fellow members of the committee after The Herald revealed figures showing barely a quarter of requests for action were accepted for consideration by MSPs.

The figures, obtained under Freedom of Information, showed 649 petition proposals were submitted between 2011/12 and 2014/15 but only 170, or 26 per cent, were considered by the committee.

The rest were rejected as unsuitable by parliamentary clerks.

The equivalent committee in the Welsh Assembly considered twice as many petitions over the same period.

The figures prompted calls from committee members for a review of rejected proposals and greater transparency in the way they were recorded.

But in a statement issued through the parliament, Labour MSP Mr Pentland said: "For a petition to be taken forward it must call for action that is within the parliament’s power to take.

"It must also relate to a national policy or practice, as opposed to a local or individual concern.

"Unfortunately, the Herald article does not reflect this, or the difference between petitions that are submitted and proposals or enquiries about potential petitions.

"As such it is disingenuous to present these figures as petitions being blocked by parliamentary staff."

He added: "The parliament actively encourages the public to engage with the petitions system."

Committee members John Wilson, an Independent MSP, and Hanzala Malik, one of Mr Pentland';s Labour colleagues, said they would seek more information about rejected petitions when Holyrood returns from its summer break next week.

Petitions currently under consideration include a call for murderers to serve "whole of life" sentences and a request for measures to improve the welfare of pet rabbits.
