According to reports, Dyson was responding to an e-mail sent to her and thirty others by boyfriend Alex Hewson, when she accidentally clicked the 'Reply to all' button.
While the e-mail began innocently enough, asking Alex to pick her up from the airport on her return from a week's work in Australia. She then wrote: "I have to write a sucky 'thank you' email to clients now, w*nk w*nk" – and went on to discuss phone sex. The unintended recipients could not resist forwarding the e-mail.
It has now circulated the globe, being read by millions of e-mail users – including Dyson's employers, Hobsons. Helen Symonds, communications manager at the firm of career advisers, told reporters: "We have staff procedures in place to deal with any incidents of this nature."
She added: "We want to make clear that all e-mails made by staff members reflect their own personal views and don't reflect the views of the company."
