The former army officer has criticised the government's defence cuts, saying the Conservatives would increase spending. He served as minister for the armed forces under John Major.

JOHN THURSO MP

Career: Johann Hari is a columnist for the Independent newspaper, and writes regularly for the gay magazine Attitude and the New Statesman.
Aged just 25, he has already written his first book, God Save the Queen?, a critique of the monarchy, and written a play, Going Down in History, which won critical acclaim at the Edinburgh Festival.
In 2003 he was named Young Journalist of the Year by the Press Gazette awards. A Cambridge graduate, he was also the Times Student Journalist of the Year in 2000.
HEATHER MILLS McCARTNEY
Title: UN Goodwill Ambassador
Career: Heather has spent 11 years campaigning to rid the world of land mines and was nominated for a Nobel Peace Prize in 1996.
A former model, Heather Mills McCartney threw herself into the media spotlight by inviting journalists to her bedside after losing part of a leg in a road accident in 1993.
Her husband, Sir Paul McCartney recently accused the press of "spiteful" treatment of his wife since they wed in 2002.
