The decision to dismiss Julian Smith as Secretary of State for Northern Ireland was criticised by a number of prominent political figures in Northern Ireland, including SDLP leader Colum Eastwood who described the move as showing "dangerous indifference" by the Prime Minister. Smith had been widely seen as instrumental in securing a cross-party deal to restore the Northern Ireland Executive, after three years without a devolved government in Stormont. Tributes to Smith's tenure as Northern Ireland Secretary were paid by NI First MinisterArlene Foster and TaoiseachLeo Varadkar. Both praised him for his role in ending the political deadlock in the country. Many political commentators expressed their surprise at Smith's dismissal, given his perceived success during his time as Secretary of State for Northern Ireland. Some suggested that Smith's testimony to the Northern Ireland Affairs Select Committee in October 2019, in which he described a potential no-deal Brexit as being "a very, very bad idea for Northern Ireland", had influenced the decision to remove him from his position. Stephen Bush, political editor of the New Statesman, speculated that the consequence of Johnson's removal of Smith would be the destabilisation of the new power-sharing agreement and increased difficulty in negotiating the details of the "New Protocol".
Resignation of Sajid Javid
Tensions between 10 Downing Street and the Treasury had come to a head in August 2019, when the Prime Minister's Chief Special Adviser Dominic Cummings dismissed one of Chancellor Sajid Javid's aides, Sonia Khan, without Javid's permission and without informing him. It was alleged that, during her dismissal, Cummings "went outside No 10 and asked an armed officer to enter the building and escort Khan off the premises." In November 2019, following questions of a rift between the two men, Johnson gave his assurance that he would retain Javid as Chancellor after the 2019 general election. However, in the weeks leading up to the reshuffle, a number of briefings in the press had suggested that a new economic ministry led by Rishi Sunak might be established, to reduce the power and political influence of the Treasury. Sunak was considered to be a Johnson loyalist, seen as the "rising star" minister who had ably represented the Prime Minister during the 2019 election debates. By February 2020, it was reported that Javid would remain in his role as Chancellor and that Sunak would stay on as Chief Secretary to the Treasury, in order to "keep an eye" on Javid. On 13 February 2020, the day of the reshuffle, Javid resigned as Chancellor of the Exchequer, following a meeting with the Prime Minister. During the meeting, Johnson had offered to allow Javid to keep his position on the condition that he dismiss all his advisers at the Treasury and replace them with ones selected by 10 Downing Street. Upon resigning, Javid told the Press Association that "no self-respecting minister would accept those terms". The Chancellor's resignation had been unexpected, given Johnson's commitment to keep him in the Cabinet and recent reports that a rival finance ministry would not be created. Robert Shrimsley, chief political commentator of the Financial Times, warned that the Prime Minister's handling of his relationship with Javid could damage the government. He argued that "good government often depends on senior ministers – and the chancellor in particular – being able to fight bad ideas. Mr Johnson's cabinet has just seen the price of defiance".
