Labour also made gains, while the Liberal Democrats experienced meltdown, losing over half their seats and falling behind the Conservatives.
In October 2010 a new company - Logica was awarded the contract for the vote counting system for the 2012 council elections, and since January 2011 testing has been under way to sort out many issues.
The Liberal Democrats continued to experience a political meltdown following on from the previous year's Scottish elections, losing 57% of their councillors.
In the Fife Council ward of Buckhaven, Methil and Wemyss Villages, the party's candidate, Lois Lothian, received just 21 votes.
The Greens boosted their councillor numbers from 8 to 14, including doubling their representation in Edinburgh (where they topped the poll in two wards for the first time) and electing councillors for the first time to Stirling, Midlothian and Aberdeenshire local authorities (note: Cllr Martin Ford, re-elected in 2012 as a Green, won in 2007 as a Liberal Democrat).
Note: The net gain/loss and percentage change in number of votes relates to the result of the previous Scottish local elections on 3 May 2007.
