Johnson, in an effort to minimize disruption from the cabinet reshuffle, swiftly appointed Rishi Sunak, Javid's deputy and a staunch supporter of the prime minister, to fill the vacant position. The reshuffle was carefully planned by the prime minister's team to showcase new talent, particularly women, while also rewarding loyal supporters to help achieve his vision for Britain post-Brexit. However, Javid's resignation as finance minister, possibly at the behest of Johnson's team, due to a disagreement over advisers, reinforced the perception that the prime minister does not tolerate dissent within his government. A source close to Javid revealed that he rejected the role of Chancellor of the Exchequer because Johnson demanded he dismiss his advisers and replace them with individuals from the prime minister's office. The Chancellor stated that no minister with self-respect would agree to those conditions. Sunak, who has a background in investment banking and is married to the daughter of an Indian billionaire, is viewed by many Conservatives as a reliable individual who will support Johnson's plans for a post-Brexit Britain. The appointment of Sunak led to an increase in the value of the pound as investors anticipate a more expansive budget next month. Johnson has committed to bridging the wealth and opportunity gap in various parts of the country by directing resources to northern and central England, where he gained support from traditional Labour Party voters. It was unexpected that Johnson would make significant changes to his government, opting for minimal adjustments. However, even the minor changes in the lower levels of government provided some insight into his efforts to increase his control over power. By firing Northern Ireland minister Julian Smith, who had recently played a role in restoring a government in the British province, Johnson faced criticism from politicians in both Ireland and Northern Ireland. Smith, who had previously overseen parliamentary discipline for Theresa May, was the first minister to be dismissed in the reshuffle. Along with Smith, business minister Andrea Leadsom and environment minister Theresa Villiers were also let go. Alok Sharma, a loyal former minister for international development, was appointed as the new business minister and tasked with leading the COP26 climate change summit in Scotland in November, an event expected to be attended by world leaders. However, it was Javid's decision that disrupted the 'business as usual' appearance that Johnson had intended to convey. Downing Street aides had previously downplayed the idea of major changes, despite Dominic Cummings' public desire for a radical government reorganization. A source from Johnson's office stated that the prime minister aimed to use the reshuffle to lay the groundwork for the present and future government, and to highlight new talent, especially women. Johnson prioritized loyalty in order to fulfill his agenda and uphold the promises he made before the December 12 election, in which he secured a significant majority. Nonetheless, opposition politicians criticized the reshuffle as chaotic. John McDonnell, the finance spokesman for the main opposition Labour Party, stated that this is a historical document depicting a government in disarray shortly after an election.
