From a 'mixed' family, her father was not a Catholic, she worked for the Richmond Herald and later the Surrey Comet newspaper after leaving school. Bogle has written a weekly column for the Catholic Times and has been described by liberal Catholic writer Peter Stanford as "a forceful, eloquent and youthful firebrand who has made it her business, with some success, to act as a counter-balance to Ms [Cristina] Odone on the chat-show and soundbite circuit."

Bogle's biography of nineteenth century humanitarian Caroline Chisholm The Emigrant's Friend was published in 1993. Bogle's current project is a work about Mother Riccarda Beauchamp Hambrough and Sister Katherine Flanagan, two British Bridgettine nuns in Rome who hid 50 Jewish refugees in their guesthouse during the Nazi occupation.

Bogle is a founder member of the Association for Catholic Women in England and a contributing editor to the Catholic journal Voices.She married Australian-born Jamie Bogle, now a barrister, in 1980.

A conservative who believes the Catholic Church should advocate fundamental truths rather than liberal attitudes; Bogle is opposed to the ordination of women priests. In 1999 Bogle opposed the recommendation of the Broadcasting Standards Commission to use BCE and CE in place of BC and AD. In 1998 though, she criticised the decision of the church to honour Rupert Murdoch with a knighthood: "It sends out the message that you can make a living out of something - soft pornography - that is regarded by the Church as sinful, and yet you can be awarded for it. The Knighthood of St. Gregory is supposed to be about honour and chivalry and and splendour. To give it to Murdoch is ridiculous and wrong."

She believes Catholics, and Christians generally, are under sustained assault in the UK and should assert themselves more. According to Peter Stanford Bogle's criticism of the hierarchy represents a minority of Catholics in Britain. In March 2009 Bogle participated in a debate on Channel 4 News with Dr Rachel Baggaley Head of Christian Action's HIV programme and presenter Jon Snow on the church's policy towards AIDS in Africa which Snow himself has described as the fierciest debate in which he has been involved.
