Britain's Finance Minister Rachel Reeves is set to issue a stern warning to her successor in her final Mansion House speech before Andy Burnham takes over as Prime Minister next week. According to latest reports, Reeves will use her third Mansion House speech to tell City chiefs that the next government must "maintain" fiscal credibility and stability. As reported by Reuters, Reeves is expected to say "Because of the choices I have made, I'm proud to report that the British economy is strong." She will emphasize that "That change is only possible if we maintain the credibility that we have earned, and the stability that we have built, with growth and opportunity in every town, city and region of the UK." This represents her final attempt to defend her economic record after two years in office ahead of the overthrow of Labour's election-winning leadership.
The former Greater Manchester mayor Andy Burnham is expected to be formally announced as Labour leader on Friday and will be officially named prime minister on July 20. Burnham has outlined plans to boost economic growth across every region of the UK, accelerate the devolution of powers away from London and expand the country's stock of social housing. As reported by Reuters, despite the leadership change, Burnham has pledged to retain the fiscal rules established by Reeves and uphold Labour's 2024 election commitment not to raise taxes on working people. The finance ministry said both priorities will remain central to the government's economic agenda as Labour prepares for a new administration, with Burnham's commitment to preserving Reeves' fiscal framework likely to reassure financial markets by reducing the risk of a major shift in budget policy. However, Reeves had signalled her hope to cling on to her position as chancellor following the resignation of Keir Starmer, telling top City leaders last month she had "unfinished business in fiscal devolution" in a nod to Burnham's plans to give greater powers to regional governments, but those hopes quickly faded as the incoming Burnham team refused to rule out a shake-up at the Treasury.
Britain's economy under Reeves has delivered significant improvements, with the UK having the fastest economic growth in the G7 at the start of this year. According to Reuters, the next finance minister is expected to inherit mounting economic challenges, including slowing growth prospects and persistent inflationary pressures. However, Reeves will highlight key achievements including borrowing falling from 5.2% to 4.3% - its lowest level in six years, investment up, productivity up, and wages up too. She will also point to waiting lists falling faster than at any time in the last 17 years and half a million children will be lifted out of poverty by the end of this Parliament. Burnham's commitment to preserving Reeves' fiscal framework is likely to reassure financial markets by reducing the risk of a major shift in budget policy, with stable public finances potentially supporting investor confidence in UK government bonds and the British pound at a time when concerns over slowing economic growth and elevated inflation continue to weigh on sentiment.
UK-listed companies with significant domestic exposure, including banks, housebuilders, retailers and infrastructure firms, could remain in focus. As reported by Reuters, Burnham's proposals to expand social housing and increase regional investment may benefit construction and housing-related stocks if backed by higher public spending. Companies linked to artificial intelligence, technology and export-oriented industries could gain over the longer term if the government follows through on plans to deepen economic ties with the European Union and accelerate AI adoption, although investors are likely to wait for concrete policy announcements before adjusting their market expectations regarding the new administration's economic direction. In her final speech, Reeves is expected to praise financial services as "the crown jewel in the UK economy and a shining example of our potential as a nation," alongside laying out a path toward loosening bank capital rules. She will be joined by Dame Susan Langley, Lady Mayor of the City of London, who will unveil plans for a new AI platform to accelerate investment into British infrastructure projects.
Other potential candidates include Energy Secretary Ed Miliband, who is the bookmakers' favourite to succeed Reeves, along with Pat McFadden, the secretary of state for work and pensions, and former health secretary Wes Streeting, both of whom are considered leading contenders as Burnham prepares to form his cabinet. According to Reuters, Reeves is Britain's first female chancellor of the exchequer, adding historical significance to her tenure. Miliband is reportedly poised to approve fresh gas exploration licences in the North Sea, overturning months of staunch opposition to the projects, in the clearest sign yet the former party leader is vying for the job. Investors are likely to wait for concrete policy announcements before adjusting their market expectations regarding the new administration's economic direction, with the leadership transition adding another layer of uncertainty to an already challenging economic environment.
