New prime minister Rishi Sunak will be the UK's third prime minister in the space of just a few weeks. After just 44 days in the top job, Liz Truss announced she would be moving out of Number 10, following a period of market turmoil triggered by her economic plans.
Over the last week, Tory MPs have been throwing support behind various potential candidates, including former PM Boris Johnson, before deciding on Mr Sunak. The MP for Richmond was defeated just seven weeks ago in the last Tory leadership race as the party membership picked rival Ms Truss, garnering 60,399 votes to her 81,326.
His supporters have highlighted his “calm competence”, suggesting he is a “serious person for serious times”.
