The woman whose voice can be heard across the Tube network in her role as the official "announcer" has been axed after releasing a series of spoof announcements.

Emma Clarke has been the "voice of the Tube" for eight years, urging passengers to "mind the gap". But in a series of spoof messages posted on her website, the 36-year-old married mother of two attacked the transport system, claiming she avoided it at all costs.

Also singled out for mockery were American tourists, Sudoku solvers and peeping Toms. "We'd like to remind our American tourist friends that you are almost certainly talking too loudly," she says in one message.

In another, she warns: "Would the passenger ... pretending to read a paper but who is actually staring at that woman's chest please stop. You're not fooling anyone, you filthy pervert."

But now the parent company of the Tube has made an announcement of its own. A TfL spokesman said: "Some of the spoof announcements are very funny. But Emma is a bit silly to go round slagging off her client's services. London Underground is sorry to have to announce that further contracts for Miss Clarke are experiencing severe delays."

Ms Clarke today said she was "very disappointed" at TfL's reaction. Speaking from her home in Altrincham, Cheshire, she said: "I don't feel that I have been slagging them off - that was never my intention. It was just a bit of a laugh, I think they have missed the point of what I was trying to do."

The voiceover artist and writer put the messages on the website she set up earlier this month after canvassing friends on what they would most like to hear.
