Sue Gray, the former senior civil servant best known for leading the “partygate” investigation, will formally take her seat in the House of Lords on Tuesday, just four months after stepping away from the centre of government.
Ms Gray, who later became Sir Keir Starmer’s chief of staff, was among 30 new Labour peers announced by Downing Street last December, as the government sought to address what it described as an imbalance in the upper chamber. Her appointment is part of a wider intake that includes six new Conservative peers, such as Liz Truss’s former deputy prime minister Dame Thérèse Coffey, and two Liberal Democrat nominees.
She will be introduced to the House as Baroness Gray of Tottenham, alongside Baroness Cash, a Conservative appointment.
A career defined by controversy and change
Sue Gray was once a relatively unknown but highly influential figure in government, responsible for upholding conduct and propriety within Whitehall. However, she became a household name in 2021 when she took over the investigation into breaches of Covid-19 restrictions in Downing Street – a scandal that ultimately contributed to Boris Johnson’s downfall as prime minister.
Her role in the “partygate” probe arose after then-cabinet secretary Simon Case, her superior, was forced to step back due to revelations that his own office had allegedly held a Christmas gathering during lockdown. Ms Gray’s report, which detailed multiple rule-breaking events within government circles, fuelled widespread public and political anger, and intensified scrutiny on Mr Johnson’s leadership.
Joining labour and political fallout
Despite decades of service in Whitehall, Ms Gray’s reputation for impartiality was called into question when she left the civil service to join Labour as Sir Keir Starmer’s chief of staff in 2023. The move was heavily criticised by Conservative MPs, who argued that it undermined the neutrality expected of senior civil servants.
Further controversy followed after Labour’s landslide victory in the 2024 general election. Leaked disclosures revealed that Ms Gray earned a salary exceeding that of the Prime Minister, and reports emerged of internal tensions within Downing Street, with claims of a power struggle between her and other key advisers.
As speculation intensified, Ms Gray announced her resignation in October, stating that she was “becoming a distraction” to the new government. She had been slated to take on a newly created role as “envoy to the nations and regions” after a break from frontline politics, but in November, Number 10 confirmed that she would not be taking up the position.
Elevation to the lords
Despite her abrupt departure from Downing Street, Ms Gray’s influence within Labour remains significant. In December, she was one of 30 new Labour appointments to the House of Lords, a move aimed at strengthening the party’s presence in the chamber.
A Labour source at the time defended the decision, arguing that the Conservatives had created a long-standing imbalance in the Lords that needed to be addressed. Labour has also pledged to reform the upper chamber, including tackling its gender disparity – reflected in the fact that 17 of the 30 new Labour peers are women.

Political implications
Ms Gray’s appointment increases Labour’s presence in the Lords, where the party previously had 187 peers compared to 273 for the Conservatives. While this still leaves Labour in a minority, the additional support in the unelected chamber could help the government push through key legislation.
However, her elevation is unlikely to silence critics. Some Conservative MPs continue to argue that her move from the civil service to Labour raises ethical concerns, while others claim her rapid return to public life shows Labour’s willingness to reward political loyalty.
For Sir Keir Starmer, Ms Gray’s presence in the Lords may serve as both an asset and a reminder of the challenges that have come with his party’s transition to government. While her expertise in governance and administration remains valuable, the circumstances of her political journey ensure that she remains a divisive figure within Westminster.
As she takes her seat in the Lords, Baroness Gray of Tottenham will begin a new chapter in her career—one that is likely to be watched closely by both allies and opponents alike.
