Health secretary will describe plan to offer tax relief on private healthcare as ‘tax cut for the wealthiest’

Reform UK’s policy of tax relief on private health insurance could cost the country £1.7bn, the health secretary, Wes Streeting, is expected to say on Saturday.

Streeting will make the claim at a conference organised by the Fabian Society, a socialist thinktank aligned to the Labour party, and will describe the Reform proposal as a “tax cut for the wealthiest”.
