On his party's future: "A Conservative Government will scrap the prescriptive, bureaucratic standards that stifle innovation, hamper brown field development and promote monotonous, uniform housing estates. We will emphasise quality of design, rather than compliance with government diktats."
What the press says: "Tim Yeo has been modest and realistic enough to suggest that he will lead the way in retiring early, showing leadership over his lack of leadership abilities," Steve Richards, The Independent.
Former shadow transport and environment secretary Tim Yeo has been an MP since 1983. His career, when the Conservatives were in power, was one of steady progress.
He served as a parliamentary private secretary to Douglas Hurd and then as a junior minister in the Departments of Health and the Environment - until he was obliged to resign in 1994 when he was revealed to have fathered a child by a Tory councillor and narrowly avoided deselection by his local party.
William Hague revived his political career and, as shadow agriculture minister, Mr Yeo was credited with providing the government with constructive opposition during the foot-and-mouth crisis of 2001.
He retained his place in the shadow cabinet under Iain Duncan Smith despite his vociferous support for Michael Portillo's leadership bid.
One of the more socially-liberal Conservatives, he was appointed shadow trade and industry secretary in IDS' reshuffle in July 2002.
Under Michael Howard's leadership, he took up the "super-brief" of covering both health and education as shadow secretary for public services.
Those roles were later split, and Mr Yeo became shadow secretary of state for both transport and environment, food and rural affairs.
He quit the shadow cabinet after May's General Election, saying he wanted to be free to play a role in rethinking the party's future.
