Ambulance waits in Health Secretary Steve Barlcay's own constituency are among the worst in the country, figures have revealed.
Category one patients - the most severe - waited on an average of 14 minutes for an ambulance to arrive in Mr Barclay's parliamentary seat of North East Cambridgeshire.
The target NHS time for responding to calls involving life-threatening injuries, including cardiac arrest and serious allergic reactions is 7 minutes on average.
