Cllr Daniel Meikle was shocked by a letter from Mr Taylor to Scottish secretary Michael Forsyth in which he said it 'had been put to him' that cllr Meikle - the then planning chairman in waiting of South Lanarkshire Council - took part in consideration of a planning application when he was previously employed by, or a consultant to, a rival company of the developer.
Mr Taylor is the parliamentary adviser to the opencast mining company involved, Law Holdings of Uddingston, which was seeking planning consent from South Lanarkshire predecessor Clydesdale DC.
Cllr Meikle said although he owned a company, Meikle Construction, he had no connection with the firm mentioned in the MP's letter, The Scotsman reports.
Clydesdale Labour MP Jimmy Hood has reported Mr Taylor to the commissioner. Mr Taylor said he has accepted the suggestions in his letter were without foundation, and he had recorded in the letter that he was a consultant to Law Holdings.
