According to posts on Twitter, some Coventry City supporters have been contacting a Canadian travel company and advising them to drop Leonard Brody.
Mr Brody is due to make a key note speech for On-line Revealed Canada at a $899 per head Annual Tourism On-Line Marketing conference at the Sheraton Hotel in Toronto in early March.
However, some City supporters clearly unimpressed with Mr Brody's involvement in Coventry City FC, which has seen him resign from the board but still own shares, have contacted the conference organisers demanding that Mr Brody be pulled from the event.
