No, Britain (and any other Westminster style parliament) are party political systems, not presidential. You vote for a party, the party selects its leader. Of course your average voting citizen has not even a bare understanding of civics 101 and quite often in these circumstances various elements of the press demand a new election in order to make certain the PM has a mandate, if it suits their purposes. Personally I think it's quite likely to turn out as you suggest, Boris is going to fail to negotiate even the slightest terms from Europe and will call a snap election at some point where the parties themselves will campaign on in or out, where both Labour and Conservatives will be in.
