What factors may arise from the PM using Patronage?

-PM has to Satisfy the Various Factions in the Political Party (Thatcher at the Start appointed 'Wets' who disagreed with her New Right) -Safer to have Possible Rivals as the CRM shuts them up (Cameron and May felt good having Johnson in Cabinet rather than a Backbench MP) -Type of Government affects Patronage (Coalition makes the PM promote MPs from the Partner - Cameron with 5 Lib Dems to Cabinet. Small Majority / Hung, May promoted 'Brexteers such as David Davis to Senior Posts) -Ministers may Refuse taking up a Job (May in January unsuccessfully reshuffled the Cabinet in 2018 because Jeremy Hunt refused to move from Health Secretary)
