How can the UK transition power to a new government overnight?

Question

Other countries like the US have a months long gap before an elected official actually takes power.

In: Other

Answer 1

The US gap is a result of constitutionally mandated timelines, rather than some physical inability to transition faster.

Given the opposition in the UK has already hammered out the cabinet, in the form of the Shadow Cabinet, abd the members of that cabinet are all already Members of Parliament, it doesn’t need to wrangle a leadership team after the elections and can just make the transition as soon as the dust settles.
