Lush began working for the BBC as a trainee secretary in 1970 at what is now
Langham Hotel, London, but was then owned and used by the corporation. After nine years, she became a researcher. Lush told Gaby Koppel in 2018: "I think I was quite lucky in that I found myself working for women bosses at crucial times and they took me more seriously and encouraged me much more than my previously male bosses had done, to believe in myself". After periods as a production assistant and a producer working in presentation, Lush commissioned such shows as
The Weakest Link, the soap
Doctors and
Bargain Hunt. She chose
Anne Robinson for
The Weakest Link and brought
Graham Norton and
Vanessa Feltz to the BBC. In 2008, former BBC newsreader
Natasha Kaplinsky told how she felt Lush and her junior managers had intimidated her into participating in the BBC's high-profile
Strictly Come Dancing entertainment programme in 2003. After Kaplinsky refused to participate for 6 months, the matter was escalated to the
BBC One Controller,
Lorraine Heggessey and when that approach failed, Lush, Head of Entertainment took Kaplinsky aside and told her "I'm sure you're not going to be penalised for not doing it". ==Later career==
