Sources cited in The Times say that in seeking the resignation of chancellor Javid British prime minister Boris Johnson wanted to avoid early on the situation that existed between prime minister Cameron and Chancellor Osborne of differences in policy. There were differences between Mr. Johnson and Mr. Javid on balancing the budget and the appointment of the Governor of the Bank of England. Mr. Johnson and adviser Cummings wanted looser fiscal rules to achieve the levelling-up agenda, infrastructure spending, than Mr. Javid.  A decision on HS2 was to come from the prime minister alone not the chancellor. At one point 10 Downing Street communicated directly with the chief secretary of the Treasury, Mr. Sonak, who is now the new chancellor. Mr. Sonak 39, was only recently a junior minister. 

Critical for Mr. Boris Johnson and advisor Mr. Cummings is the agenda of infrastructure and leveling up the country. It became apparent that finance would be critical for policy and investments to achieve this. It was then decided to set policy at No. 10 Downing Street and be sure that this was carried out by the chancellor and all ministers as the new way of operating. Mr. Johnson sees an opportunity to make changes for the long term through a long period in office and wanted a tight knit team right from the beginning.
