The former leader of Glasgow City Council, Charlie Gordon, has spent the first day in his new job at the Scottish Parliament.
Charlie Gordon is greeted by the first minister
The Labour MSP, who was elected to represent Glasgow's Cathcart constituency last week, was greeted at Holyrood by Jack McConnell.
Mr Gordon told the first minister he was "reporting for duty."
The Cathcart by-election was prompted by Mike Watson's resignation following his fire-raising conviction.
Mr Gordon was accompanied by Greenock and Inverclyde MSP Duncan McNeil who was his campaign manager during the by-election.
Round of applause
The Scottish Labour leader congratulated both men for running a "great campaign".
Labour managed to fend off a challenge from the SNP who had tried to exploit local concerns about hospital services , the future of Scottish Power and the Iraq war.
Mr Gordon was led into Queensberry House for Labour's weekly parliamentary group meeting where he was given a round of applause by the party's other MSPs.
