To ask the Scottish Executive, further to the answer to question S2W-28407 by Tavish Scott on 6 October 2006, what the reasons are for the delay in the commencement date of the construction of an off-line improvement to the carriageway of the A737 at the Den, between Dalry and Beith; what the Executive’s source was for the earlier anticipated commencement date of June 2006, as referred to in the Minister for Transport’s letter to me dated 12 September 2005, and how many of the decisions referred to in the answer to question S2W-28407 had been reached prior to June 2006.
