It’s some time since Foulkes made the above statement (2008) revealing the depths of the Labour gene pool in Scotland, so I can’t source the claim in my headline.
The facts, however are the facts.
In 2002, the Child Poverty Action Group (CPAG) produced this list list of the UK’s bottom ten, poorest constituencies, a few years before the first SNP government:
Camberwell and Peckham
Bethnal Green and Bow

What could be causing this u-turn in Scotland’s poverty situation? These SNP actions?
- The Bedroom Tax.

- Scotland has the highest proportion of employees being paid at least the real Living Wage of all four UK nations.
- Scotland has the smallest gap between median pay for the disabled and non-disabled.
- Only Scotland and Wales pay the living wage to all NHS employees and Scotland was first to pay the living wage to all public-sector employees.
- Scottish care workers have been receiving the Living Wage of £8.45 per hour since 2016 and receive the same rate for all ‘sleepover hours worked.
- In 2019, the funeral support payment.
