In 1994 Central was taken over by Carlton after the ITV franchise carve-up of 1992.
In 1995 Spitting Image production was axed, with last episodes airing Jan 1996.

Most of the original writers and Impressionists had left.
Plus Blair had just got elected Labour leader, and at that point was un-satirisable due to the unpopularity of the Tories.
