Johnson quickly appointed Rishi Sunak, Javid's deputy and a strong supporter of the prime minister, in order 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, while also rewarding loyal supporters. However, Javid's resignation as finance minister, possibly at the request of Johnson's team due to a dispute over Javid's advisers, suggested that dissent would not be tolerated in the government. Javid declined to sack his advisers and replace them with those from the prime minister's Downing Street office. The Chancellor stated that no minister with self-respect would agree to those conditions. Sunak, who has a background in finance and is married to the daughter of a wealthy Indian individual, is viewed by many Conservatives as a reliable individual who will support Johnson's plans for post-Brexit Britain. The appointment of Sunak led to an increase in the value of the pound as investors anticipated a more expansive budget in the upcoming month. Johnson has pledged to address the wealth and opportunity disparities in different parts of Britain by directing investments to regions in northern and central England where he gained support from traditional Labour Party voters. Johnson had not been expected to make significant changes to his government, opting to keep alterations to a minimum. However, even the minor changes in the lower levels of government provided some indication of his desire to strengthen his control over power. The dismissal of Northern Ireland minister Julian Smith, who had recently played a key role in restoring a government in the British province, was met with criticism from politicians on both sides of the Irish border. Smith, who had previously overseen parliamentary discipline for Johnson's predecessor, Theresa May, was the first minister to be removed in the reshuffle. He was joined by business minister Andrea Leadsom and environment minister Theresa Villiers. Alok Sharma, a staunch loyalist 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 is expected to be attended by world leaders. Javid's decision disrupted Johnson's plan for maintaining the status quo in his government. The idea of major changes had been downplayed by Downing Street aides, despite Dominic Cummings' desire for a radical reorganisation. Johnson's office stated that the reshuffle aimed to establish a strong foundation for the government moving forward and to highlight new talent, especially women. Johnson prioritized loyalty in order to fulfill his election promises and agenda. 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 shortly after an election.
