Louise Haigh: First Secretary of State, Sheffield Heeley MP and Career Explained

Introduction

Louise Haigh is the First Secretary of State, Chancellor of the Duchy of Lancaster and Minister for the Cabinet Office, appointed on 20 July 2026 in Andy Burnham’s first Cabinet. It is the highest-ranking Cabinet post after the Prime Minister, and it makes Haigh the minister who stands in for Burnham at events such as Prime Minister’s Questions when he is away. For a politician whose first spell in Cabinet lasted barely four months, the appointment is one of the most striking comebacks in recent British politics.

Haigh has been the Labour MP for Sheffield Heeley since May 2015, and she is a long-standing ally of Burnham, having run his successful by-election campaign and his transition team. Her career runs from trade union organising, through a spell as a special constable and a job in insurance, into the shadow cabinet and then, twice, into government.

Quick Bio

Sheffield roots and the road to Westminster

Haigh was born and brought up in Sheffield, on Abbeydale Road, and she still lives in the city, in Norfolk Park. That local anchor has been the constant of her politics: in her acceptance speech on first being elected she told Sheffield Heeley that its people would always be her number one priority, and she has repeated the point at every election since.

Before Parliament she worked in roles that explain her later interests. She served as a special constable in the Metropolitan Police between 2009 and 2011, worked as a public policy manager for Aviva from 2012 to 2014, and was a shop steward for the Unite union. She studied politics at the University of Nottingham and law at Birkbeck, University of London. Policing, insurance and union organising gave her three different views of the same problem: how large institutions treat ordinary people, and what happens when they get it wrong.

She was elected MP for Sheffield Heeley in May 2015, at the election that returned David Cameron’s Conservative government, and she was re-elected at every election after that, increasing her vote share to 55 per cent at the 2024 general election. Sheffield Heeley is a seat Labour has held throughout her tenure, but Haigh has never treated it as safe: her constituency work, and her reputation as a campaigning backbencher, were built long before she reached the front bench.

The shadow cabinet years

Haigh’s frontbench career began in July 2017, when she was appointed Shadow Policing Minister. Drawing on her time as a special constable, she campaigned for the police to be properly resourced, staffed and accountable, arguing that neighbourhood policing had been hollowed out by cuts. It was a brief that suited her background and her style: detailed, persistent and rooted in the experience of frontline workers.

In April 2020 she moved to Shadow Secretary of State for Northern Ireland, and in November 2021 she became Shadow Secretary of State for Transport. In the transport brief she argued that public transport should be affordable, accessible and reliable, and she made the case for public ownership and investment in rail and buses. By the time Labour won the 2024 election she was one of the shadow cabinet’s most recognisable figures, and her appointment as Transport Secretary in Keir Starmer’s first Cabinet looked like the natural next step.

Haigh was a key figure on the soft left of the Labour Party, willing to organise opposition inside the party when she thought the leadership was wrong — including, reportedly, during the welfare cuts rebellion, when MPs were organised to threaten to vote against controversial reforms. That vote-counting skill is, in effect, the skill set of a Cabinet Office minister.

Transport Secretary — and a four-month tenure

Haigh was appointed Secretary of State for Transport on 5 July 2024, aged 36, making her the youngest-ever female Cabinet minister at the time. She took over a department facing rail reform, bus franchising and the long aftermath of the pandemic’s effect on travel. Her tenure, however, lasted only until 29 November 2024.

On 28 November 2024 it emerged that Haigh had pleaded guilty to fraud by false representation in 2014, after falsely reporting to police in 2013 that her work phone had been stolen during a mugging. She had been investigated by her then employer, Aviva, and given a conditional discharge by magistrates. She resigned as Transport Secretary the following day. The episode ended her first Cabinet career, and for eighteen months it looked as though it might have ended her ministerial career altogether.

It is worth stating the facts plainly, because competitor biographies often blur them. The offence was committed in her twenties, before she entered Parliament. It was not a conviction for an offence committed in office, and it did not involve public money. What ended her tenure was the political fact that a Cabinet minister’s past conviction, once public, became untenable — not a new allegation. Haigh herself did not dispute the facts when they emerged.

The comeback: First Secretary of State

After Keir Starmer’s resignation, Andy Burnham became Prime Minister and, on 20 July 2026, appointed Haigh First Secretary of State, Chancellor of the Duchy of Lancaster and Minister for the Cabinet Office. She is the first minister to hold the First Secretary title since Dominic Raab, who held it from 2019 to 2021 alongside the Foreign Secretaryship, and she succeeds Darren Jones and Nick Thomas-Symonds in the Duchy and Cabinet Office roles respectively.

The job is deliberately broad. As Chancellor of the Duchy of Lancaster she administers the Duchy’s estates and rents. As Minister for the Cabinet Office she oversees the civil service and state reform. As First Secretary she coordinates cross-government priorities and stands in for the Prime Minister. In practice, she is Burnham’s deputy in all but name: the minister who makes the government machine work, and who carries his authority when he is absent.

The appointment also reflects a political debt. Haigh is one of Burnham’s closest allies, and she ran both his by-election campaign and his transition into Downing Street. Prime ministers tend to put their most trusted lieutenants in the Cabinet Office, because it is the department that sees everything and controls the diary, the appointments and the flow of decisions.

What competitor biographies get wrong or leave out

1. They still call her Transport Secretary. That role ended in November 2024. Since 20 July 2026 she has been First Secretary of State, Chancellor of the Duchy of Lancaster and Minister for the Cabinet Office.
2. They treat the 2024 resignation as the end of the story. The comeback under Burnham is the more interesting chapter, and it explains why the Cabinet Office role matters.
3. They miss what the Cabinet Office job actually is. It is not a ceremonial title: it covers civil service reform, state reform and coordination of the government’s priorities, and it makes Haigh the Prime Minister’s stand-in.
4. They invent personal detail. No net worth or salary figure is published here, and family detail beyond what reference sources confirm is omitted.
