In the wake of Nicola Sturgeon’s surprise resignation, it cannot be overlooked that she became leader of the Scottish National Party (SNP) after it had suffered a double blow. The party had failed to achieve its cherished goal of independence in 2014, and lost its (then) best asset, Alex Salmond.
Salmond led the SNP from the fringes to power and was often credited with its success, much as Sturgeon is now. Sturgeon, the deputy leader, had the difficulty of becoming the leader of a party whose primary purpose was independence just after it lost a referendum on the subject. It was not until after the UK voted for Brexit in 2016 (with a majority in England and Wales but not Scotland) that the SNP was able to reengage with its primary purpose.
However, with a surge of new members after 2014 and her high profile during the referendum campaign, Sturgeon had very high approval ratings after she became SNP leader. Her political rallies sold out large venues and she led her party to win 56 out of 59 seats in the Westminster election of 2015.
