Johnson quickly appointed Rishi Sunak, Javid's deputy and a strong supporter of the prime minister, in an effort to minimize disruption from the cabinet reshuffle. The reshuffle was carefully planned by the prime minister's team to showcase new talent, particularly among women, and reward loyal supporters. However, Javid's resignation as finance minister, possibly at the request of Johnson's team, due to a disagreement over his advisers, highlighted the prime minister's intolerance for dissent within his government. Javid declined the offer to continue as Chancellor of the Exchequer after Johnson insisted he replace his advisers with those from Downing Street. The Chancellor stated that no minister with self-respect would agree to those conditions. Sunak, a former employee of investment bank Goldman Sachs and the son-in-law of an Indian billionaire, is viewed by many Conservatives as a reliable individual who will support Johnson's plans for a post-Brexit UK. The value of the pound increased as investors anticipated that Sunak's appointment would lead to a more expansive budget next month. Johnson has pledged to decrease the disparity in wealth and opportunities across different regions of the UK by directing investment into northern and central England, where he gained the support of traditional Labour voters. Johnson was not expected to make major changes to his government's key positions, aiming to keep disruptions to a minimum. However, even the minor changes in the lower levels of government provided some indication of his desire to consolidate his control. The dismissal of Northern Ireland minister Julian Smith, who had recently played a role in restoring a government in the British province, drew criticism from politicians on both sides of the Irish border. Smith, who had overseen parliamentary discipline for Johnson's predecessor Theresa May, was the first minister to be removed in the reshuffle. He was accompanied by business minister Andrea Leadsom and environment minister Theresa Villiers. Alok Sharma, a staunch supporter and former minister for international development, was appointed as the new business minister and also tasked with leading the COP26 climate change summit in Scotland in November, which will be attended by world leaders. Javid's decision to resign disrupted Johnson's plan to maintain the status quo in his government. Despite previous attempts to downplay the possibility of major changes, Johnson's office confirmed on Wednesday that the prime minister wanted the reshuffle to lay the groundwork for both current and future governance, with a focus on promoting new talent, especially women. Loyalty was emphasized as crucial for Johnson to fulfill his agenda and electoral promises. However, opposition politicians criticized the reshuffle as chaotic. John McDonnell, the finance spokesman for the main opposition Labour Party, described it as a historical record of a government in turmoil just weeks after an election.
