As an MP, Ann rose through the ranks to become Shadow Health Secretary in 1998 and Shadow Home Secretary in 1999. In July 2001 she announced her decision to retire from the Shadow Cabinet, because she wanted to be able to speak on issues which she felt strongly about without the constraints of being a Front Bencher.

Her novels include The Clematis Tree (2000), An Act of Treachery (2002), Father Figure (2005), and An Act of Peace (2005).

In 2005, she appeared in a new series of Celebrity Fit Club, but this time as a panel member dispensing wisdom and advice to the celebrities taking part. Also in 2005, she presented the show Ann Widdecombe to the Rescue in which she acted as an agony aunt, dispensing no-nonsense advice to disputing families, couples, and others across the UK. In 2005, she also appeared in a discussion programme on Five to discuss who had been England's greatest monarch since the Norman Conquest; her choice of monarch was Charles II.
She was a guest host on Have I Got News for You in 2006 and 2007 and fronted a television series called Ann Widdecombe Versus, on ITV1, in which she talked to various people about things related to her as an MP, with an emphasis on confronting those responsible for problems she wished to tackle.
Issues covered included prostitution, benefits and truancy. A fourth episode was screened in September 2008 in which she travelled around London and Birmingham talking to girl gangs.
In October 2010, she appeared on BBC One's Strictly Come Dancing, partnered by Anton du Beke, winning the support of some viewers despite low marks from the judges. The couple stayed in the content for nine weeks thanks to support from the public vote. An entertaining after dinner speaker!
