The founder and chairman of the Lincoln firm Danwood has been sacked.
Colin Daniels' employment with the company was terminated this week after he was suspended along with three other senior directors.
A spokesman for the Whisby Road business said Richard Coles, Peter Hopton and David Jones would remain suspended until the conclusion of "due process".
The office printing equipment supplier has not revealed the circumstances behind the suspensions or why Mr Daniels was removed from his post.
The business, which has headquarters in Lincoln, employs around 1,800 staff in 45 sites across the country.
