Boris Johnson is likely to become the new Tory leader and prime minister, some time in the week after 22 July. If by some fluke he throws the leadership contest, almost surely someone equally hard-Brexit will win. This sharpens the choices on Brexit, and narrows further the space for temporising.
Johnson is less a right-wing ideologue, and more a mainstream opportunist, than Mario Salvini in Italy. But his choice is to project the Tories so as to appear as Brexiter as Farage (and thus recoup votes). His choice is to cut away from the EU and to veer towards Trump.
