Heidi Alexander is one of the few members of the current Cabinet who arrived in her department with experience that actually matches the job. In a political system where ministers are frequently shuffled between portfolios with little regard for expertise, that immediately distinguishes her. Having served as Deputy Mayor for Transport in London before returning to Parliament as Labour MP for Swindon South in 2024, she understands transport policy from the perspective of administration rather than theory. The question is whether competence is enough to succeed in a department where successive governments have struggled to produce visible improvements.

Her route back to Westminster was unusual. After representing Lewisham East between 2010 and 2018, she left Parliament entirely before returning six years later through a different constituency. That period outside Westminster arguably strengthened her political credibility. Most MPs spend their careers talking about public services. Alexander spent several years dealing with one of the largest transport systems in the world during a period that included the pandemic, financial crises at Transport for London, continuing Crossrail difficulties and the political battles surrounding ULEZ. Whatever view one takes of those policies, it provided practical experience that few transport ministers can claim.

That experience became one of the reasons her appointment as Secretary of State for Transport in November 2024 was received more positively than many ministerial reshuffles. Unlike some predecessors, she did not arrive needing to learn the basics of the brief.

The challenge is that understanding transport and improving transport are very different things.

Alexander inherited a department facing problems that have accumulated over decades. Britain's railways remain expensive, fragmented and heavily subsidised. Major infrastructure projects routinely face delays and escalating costs. Bus services continue to contract across large parts of the country. Road maintenance backlogs have reached levels that many local authorities openly admit they cannot afford to clear. Governments of every political colour have promised transformation. Most have delivered reviews, consultations and revised timetables instead.

Her background creates both an advantage and a potential weakness. Much of her experience comes from London, a city with transport usage, funding levels and population density unlike almost anywhere else in the country. Running transport policy for the capital is not the same as understanding the realities of rural Wales, coastal towns, former industrial communities or counties where a cancelled bus service can leave entire villages effectively isolated. A national Transport Secretary must demonstrate an understanding of both.

Politically, Alexander belongs to Labour's managerial wing. Her reputation is built around competence, organisation and attention to detail rather than ideological grandstanding. That approach may be well suited to transport, a policy area where practical delivery matters more than rhetoric. It also carries risks. The department is not short of managers. It is not short of reports, strategies or reform plans. What it lacks are visible successes that ordinary passengers and motorists can recognise.

The real test of Alexander's tenure will not be whether officials regard her as capable. It will be whether the public notices a difference. If trains remain unreliable, bus networks continue shrinking and road maintenance remains stuck in permanent backlog, competence will not be enough. Voters rarely reward ministers for understanding problems. They reward them for solving them.

Heidi Alexander enters the role with more relevant experience than most of her predecessors. That is a genuine strength. It also removes many of the excuses available to them. The Department for Transport no longer needs another minister who understands transport. It needs one who can prove that government is still capable of improving it.
