iain cumming gray -lrb- born 7 june 1957 -rrb- is a scottish politician , currently a labour party member of the scottish parliament -lrb- msp -rrb- for the east lothian constituency .
he was the leader of scottish labour in the scottish parliament from 13 september 2008 to 17 december 2011 .
he resigned following his party 's defeat in the 2011 scottish parliament elections but , due to his experience , was selected as interim leader following the resignation of jim murphy due to labour 's unsuccessful 2015 general election campaign when they won one of scotland 's 59 seats .
a former aid worker and teacher of maths and physics , gray was first elected to the devolved scottish parliament in 1999 as the msp for the edinburgh pentlands constituency , which he lost to the conservatives in 2003 .
he was returned to parliament in 2007 , for the east lothian constituency .
following wendy alexander 's resignation as scottish labour leader in 2008 , gray stood in the subsequent leadership election and was successful .
initially , gray oversaw some electoral successes for scottish labour , such as repelling snp challenges in the glenrothes -lrb- 2008 -rrb- and glasgow north east -lrb- 2009 -rrb- by-elections , as well as scottish labour maintaining all 41 constituencies it holds in the house of commons at the 2010 general election .
the 2011 scottish parliament elections proved disastrous for the party , which lost 20 constituencies as the snp won an outright majority of seats .
gray was re-elected in east lothian with a majority of 151 votes .
gray announced his resignation the day after the result , but remained in post as leader until his successor , johann lamont , took over in december 2011 .
in june 2015 , gray was appointed acting leader of scottish labour whilst a leadership and a deputy leadership election are being simultaneously held , on account of the deputy leader , kezia dugdale , resigning to run for leader .
