Forth had hoped to support Michael Portillo for the leadership of the Conservative Party, to follow Major, but Portillo famously lost his seat in the 1997 general election. Forth was then Peter Lilley's campaign manager until the latter withdrew, then supported John Redwood, and finally backed eventual winner William Hague. Forth refused the offer of a place in the Conservative shadow ministerial team and instead became a leading backbench irritant to the Labour government, engaging in "a Parliamentary form of guerrilla warfare". Initially acting as a loner and concentrating on private members bills to which he objected, Forth soon gathered a small group around him known as "the awkward squad".
