Sue Bull, finance director of the mini-conglomerate with interests in engineering and packaging, said that Mr Disbury, having been removed as chairman in July, had now resigned as a director.
Mr Disbury, understood to have earned pounds 120,000 annually, was on a three-year rolling contract. His severance terms also included a pension package.
Greg Hutchings, who heads Tomkins Holdings, took over as non-executive chairman when Mr Disbury was voted off the board.
