Original: As Salmond was still an MP in the House of Commons, Sturgeon would lead the SNP at the Scottish Parliament until the 2007 election, when Salmond was elected as an MSP.
Simplified: She became the Deputy Leader of the Scottish National Party in 2004 and because Alex Salmond was still an MP, she was the SNP's leader in the Scottish Parliament until the 2007 Scottish Parliament election. At the 2007 election, Nicola Sturgeon became the MSP for Glasgow Govan and her party formed a minority government with Alex Salmond as First Minister.
