Nestled inside a shaded courtyard, Plataran in south Jakarta offers diners the promise of authentic Indonesian food “with the atmosphere of Javanese royalty”. Five miles to the north, Kaum gives guests a taste of tribal Indonesian cooking with modern inflections.

Together, these are two of the city’s finest restaurants, and they are where Liz Truss and her team decamped, first for lunch and then for dinner, during a whistle-stop trip to the Indonesian capital in 2021. The two meals cost the taxpayer £1,443 – all paid for conveniently by handing over one of the thousands of government procurement cards (GPCs) that officials can use to pay for anything under £20,000.
