Yes but I think  ARGeezer's question, and it is a very good one, is who advises the Queen on what course of action she should take in the event of the PM refusing to resign and being unwilling to nominate someone else to take his place.

Her Majesty normally acts on the advice of the PM, and on the advice of her Privy Council, one headed by one Rees-Mogg. How could Parliament even let her know they do not want a dissolution of Parliament but wishes to proceed with another PM?

The FTPA clearly envisages the possibility of another person being asked to lead a new government in that 14 day period, but does not specify how that can come about if the PM refuses to give way and instead seeks to wait out the 14 day period and call an election.

Suppose the PM, even if he chooses to resign, decides to nominate his favourite Minister, e.g. Dominic Raab, as the next PM even though he clearly doesn't have majority support in the House. Has the Queen got discretion in whom she appoints, and on whose advice must she rely?
