CASTRIES, St. Lucia, CMC-St.Lucia's Opposition Leader Stephenson King has taken a tough stance in ongoing controversy with House Speaker Peter Foster by insisting that no leader of the opposition should ever have to apologise for doing his duty. King made his position clear in a letter to Foster's Attorney Michael Gordon, who had written to him demanding an apology "within 48 hours" for remarks he made about an alleged conflict of interest on Foster's part in the ongoing public inquiry into the St.Lucia Fire Service. King also raised the issue in a letter to Prime Minister Kenny Anthony in which he said his concerns were based on several infractions of the law as it relates to the delay in the commencement of proceedings of the Commission of Inquiry.
