Based on my limited understanding of the British Parliamentary system, it seems the Queen should be calling for new elections.
She doesn’t have that power. Under the 2011 Fixed Term Parliament Act, there are only two circumstances in which a general election can be called before the end of the term. Either the government loses two votes of confidence in the Commons within 14 days: or the Commons can vote by a two-thirds majority for an early election.
The losses this week were not confidence votes.
