Kemi Badenoch has placed the Badenoch inheritance tax plan at the centre of the Conservative Party’s offer to voters, promising to scrap stamp duty on home purchases, resist any mansion tax and abolish inheritance tax on residential property, as conference season closed with Labour and the Tories drawing the sharpest ideological lines in years.

The pledge, delivered to a receptive in-person audience, is intended to replicate the emotional force of Labour’s nationalisation agenda. Badenoch describes her overall pitch as a ‘classic old-school Conservative’ programme, built on reducing the tax burden rather than expanding the state’s reach. Inheritance tax is widely regarded as the most hated tax in the country, despite being paid by relatively few estates, and the Conservatives believe the sense of injustice it provokes gives them a durable political weapon.

Burnham sets out a rival economic offer

The contrast with Andy Burnham could scarcely be starker. As a new Prime Minister, Burnham used his conference speech to lay out an explicitly socialist programme, receiving BBC News reports of 11 standing ovations in just over an hour from an audience of activists and MPs.

His central proposition is that the state should take responsibility for the essentials of daily life: water, rail, energy and housing. To that end, Burnham announced plans to legislate to repeal what he called Thatcher’s ‘ideological ban on public ownership of water companies’, a move that signals the clearest break with the post-privatisation settlement since the utilities were sold off decades ago.

On energy, Burnham set a new ambition to bring domestic costs into line with other countries in Europe within ten years, according to the Labour Party. He also unveiled a publicly owned company branded Great British Grid, designed to speed up connections to the electricity network by driving up competition for connection projects, as BBC News reported.

Taken together, the announcements amount to a coherent argument: that state ownership of infrastructure is the route to affordable living, and that Labour’s programme speaks to voters’ aspirations just as directly as any tax cut.

The Badenoch inheritance tax plan and the question of affordability

Badenoch’s answer is to treat the Badenoch inheritance tax plan as the emotional and political equivalent of nationalisation: a policy that tells people something about who the party is and what it stands for, not merely a line in a manifesto costings document. Where Burnham frames the state as provider, Badenoch frames it as burden, and the ever-rising cost of government as a structural barrier to economic and personal advancement.

The two leaders have, in effect, produced rival theories of aspiration. Burnham thinks people get on in life when the state handles the essentials; Badenoch thinks they get on despite the state, and that lower taxes free up the energy and capital that growth requires.

The difficulty for Badenoch is fiscal. Eliminating stamp duty, resisting a mansion tax and abolishing inheritance tax on homes is a substantial package of revenue foregone. Affording it, as the piece acknowledges, will require a combination of sustained economic growth and deep cuts to public spending. Badenoch singles out the welfare budget as an area ripe for reduction, though she rules out any change to the triple lock on the state pension.

That combination will draw scrutiny. Critics will question the internal logic of a platform that promises both lower taxes and protected pensioner benefits while cutting other parts of the state. The Conservative Party will need to demonstrate to voters, policy specialists and the bond markets alike that the whole agenda is deliverable in practice, not merely appealing in a conference hall.

The onus, as Badenoch herself would accept, is now on her team to produce the detail that converts a political instinct into a credible programme of government. Labour, meanwhile, will press ahead with plans for its water legislation, and the Great British Grid announcement gives Burnham a concrete institutional vehicle around which to build his energy argument. The battle lines are drawn; the costing arguments begin now.
