"It is with deep regret that I have tendered my resignation following the decisions of the Standards Committee this week.
"I hope the events of recent days will lead to reflection by all MSPs and parliamentary officials on the appropriateness, the
objectivity and the effectiveness of our current procedures.
"I acted in good faith upon the written advice from the parliamentary authorities. I believe that there has been a breach of natural justice and a partisan decision. Nevertheless the parliamentary process, if not its conclusion, deserve respect.

"The process of successive SNP inspired complaints and investigations has been unrelenting and will continue well into the autumn, almost a year after the initial complaint.
"My pursuers have sought the prize of political victory with little thought to the standing of the Parliament. Some may feel they have achieved a political victory but wiser heads will ask at what price.
"It is clear that the vexatious complaints will continue and dominate the headlines as long as I remain Labour's Scottish Parliamentary leader. I cannot ask Labour supporters in Scotland for further forbearance.
"I have enjoyed the loyal support of my shadow ministerial team, MSPs, staff and Labour colleagues.
"I wanted colleagues to be aware of my decision as soon as possible. I am confident that Cathy Jamieson, our deputy leader, will lead the party over the summer as she has so ably done before.
"Over the last year we have made important progress on reforming the party, renewing the policies and reconnecting with voters. The SNP's first year record of broken promises, spending cuts, U turns and policy failures is daily becoming more apparent.
"I have sought to lead Labour in the Scottish Parliament with commitment and conviction without indulging in the personal attacks which have become so fashionable in current Scottish politics.
"I will of course continue to represent my constituents in Paisley North for as long as they entrust me with their support."
