However, a statement of the Scottish National Party (SNP), which Sturgeon leads, highlighted the first minister and her predecessor, Alex Salmond, had maintained a self-imposed salary freeze since 2008-2009 forgoing 20,000 pounds ($28,250) of income over the past six years.
Since 2009, SNP ministers have operated a voluntary pay freeze that has led to 250,000 of pounds ($353,125) of ministerial payments being reallocated to general public spending through the Scottish Government consolidated fund.

On Sunday, Cameron confirmed he had received 300,000 of pounds immediately following his father’s death and two further payments made a year later from his mother bringing his total inheritance to 500,000 of pounds.

Opposition Labour leader Jeremy Corbyn has still to publish his tax return and he has promised to do so soon.
