Her father was the newspaper editor Sir John Junor and her brother Roderick (1944–2000), to whom she was very close throughout his life, was a leader writer for The Daily Telegraph and speechwriter for Margaret Thatcher.
Junor was the main presenter (1988–1997) of the Travel Show Guides on BBC2 alongside Matthew Collins (Collins named 'The Special Assignments Man' did all the travelling) and John Kettley presented the weather forecast for the holiday destination for the forthcoming week or so.
Junor's other books include works on Margaret Thatcher (1983), actor Richard Burton (1986) and John Major (1993).
In 2007, she co-authored Wonderful Today with Pattie Boyd, the former fashion model and former wife of English rock stars George Harrison and Eric Clapton.
Junor assisted Sir Cliff Richard in writing the number one best selling My Life, My Way (2008) which sold over 250,000 copies and Shaun Ellis with his book The Man Who Lives with Wolves (2009).
