That always ends up happening. Whenever a government has being in power for too long they start to break into 90 different factions and spend their entire time fighting each other, and not getting anything else done.
Also a certain group of the Conservatives have started to play by the Republican Party playbook, while the rest of them are politely asking if maybe they could not be fascists? Of course appeasement never works so apparently the next best option is to have giant arguments about it and replace the PM every 10 minutes.
Fortunately Labour are another party, and regardless of what you think about them as a party, they are at least different and are less fractional currently, so perhaps now we can get something done.
