Scottish Labour has condemned a “festering culture of secrecy” within the SNP after a £33,000 salary boost for a former Westminster leader was not made public.
Angus Robertson received the salary enhancement after the SNP’s landslide victory in Scotland during the 2015 general election, when it won 56 out of 59 seats and became the third-largest party.
The now Scottish Government Constitution Secretary led his party in the House of Commons for a decade until 2017.
