 In a nutshell, there has been pretty constant political and economic turmoil during this Tory reign. First of all, five conservative prime ministers in eight years. David Cameron, who stepped down in 2016 over Brexit. The UK voted to leave Europe then, and Cameron was opposed to that, so he left. Then there was Theresa May, another casualty of Brexit. She tried to do a deal with Europe post-Brexit, failed. She left office.
