A new report from the GMB union reveals that parliamentary staff of colour earn on average £2,000 less per year than their white counterparts. The study, based on data collected after the 2024 general election, also finds that women earn £1,000 less than men in similar roles, and disabled employees earn £646 less than non-disabled colleagues.
The research, which analysed 174 cases from staff across the House of Commons and House of Lords, suggests that those with multiple protected characteristics are hardest hit. Women of colour earn almost £6,000 less annually than white men, while transgender, non-binary and gay staff also appear to face pay discrimination.
The report describes Parliament as a “very white and middle-class” environment and notes that constituency caseworkers are poorly compensated compared to those in Westminster, despite being at the “frontline” of parliamentary work. Pay gaps appear to widen over time, indicating slower career progression for staff with protected characteristics.
The GMB union says many MPs have not taken minimal action to address pay inequality. Only 17% of staff who raised concerns felt their issue was adequately addressed. The report recommends mandatory pay gap reporting and other measures to tackle discrimination.
Kartik Sawhney, senior parliamentary researcher and GMB race officer, called the findings “stark and inexcusable”, adding: “Parliament should be a model for equality, not a mirror of inequality.” Holly Williamson, the union’s parliamentary equalities officer, said: “The most emotionally demanding roles, often held by those from protected groups, are also the lowest paid. Parliament must do better.”
