On which of the following, proved charges the Finance Minister Nadhim Zahawi was sacked from the Government in February, 2023 by the British P.M. Rishi Sunak?

British Prime Minister Rishi Sunak sacked Nadhim Zahawi from his government in early 2023 following a report by the PM's independent ethics adviser, Sir Laurie Magnus. The investigation found that Zahawi had committed a "serious breach" of the Ministerial Code regarding his tax affairs. The scandal centered on a multi-million pound settlement Zahawi made with HM Revenue and Customs (HMRC), which included a penalty, related to his co-founding of the polling firm YouGov. Zahawi had failed to disclose the HMRC investigation and the subsequent settlement when he was appointed to senior cabinet positions, including Chancellor of the Exchequer. The investigation concluded he had not been transparent about his financial interests, leading to his dismissal for failing to meet the standards of integrity and openness expected of a minister.
