Sean Spicer will be bracing himself after a Saturday Night Live trailer showed Melissa McCarthy will reprise her popular impersonation of him this weekend.

The White House press secretary said he thought the exaggerated performance could have been "dialled back" as the world laughed at the comedian's parody of him in February.

But a teaser released by the NBC show suggests McCarthy will likely not go easy on Mr Spicer as she returns to host the late-night comedy show.
