Contributions to the new prime minister’s costly campaign were revealed minutes before she unveiled details of her long-awaited plan to tackle spiraling energy bills. The average donation Truss received was £20,000. Meanwhile, Rishi Sunak raised £449,570 for his failed leadership campaign. A spending cap of £300,000 was imposed by Conservative party head office at the start of the contest. Truss recorded 21 donations to her campaign, in cash and transportation costs. The largest sum came from Fitriani Hay – the wife of James Hay, who owns a luxury goods empire and is a former BP executive. He gave Truss £100,000. Other supporters included Tory peer Greville Howard, whose Westminster mansion was used by her campaign team as a headquarters. Michael Spencer also gave Truss £25,000 in early August, a week after he gave the same amount to Sunak and two weeks after he did the same for another failed candidate, Penny Mordant. Truss received £20,000 from Jon Moynihan, a former prominent member of the pro-Brexit Vote Leave campaign who called for the abolition of the Electoral Commission, along with £10,000 donated by a smoked salmon company run by ex-Brexit MEP Lance Forman . The announcement from parliament on Thursday also revealed the £23,853 cost of Johnson’s wedding party in the summer, paid for by Anthony and Carole Bamford. The couple ran JCB and footed the bill for catering, waiting staff, portable toilets, marquee hire, flowers, an ice cream van, as well as smoke and braai catering when Johnson and his wife Carrie celebrated their wedding . Truss became the heir to their support as he was awarded £5,316 in transport costs by JCB in early August.

Sunak took £50,000 from Yoginvest Ltd, a company controlled by property investor Nick Leslau, who gave the Conservatives £20,000 in 2019. Leslau told The Times in November 2020 that he would make no further donations to the party, angered by the government’s ban on commercial landlords evicting tenants. At the time he said: “I think the failure with which the property industry has been treated has been narrow-minded.”
