The A47 between Wisbech and Guyhirn was closed this afternoon after a motorist, who is now in a critical condition, was stung by a wasp and went into cardiac arrest, police have said.
A Magpas air ambulance crew provided the man with advanced life support at the scene before he was air-lifted to Kings Lynn's Queen Elizabeth Hospital after emergency services, including the police and ambulance crews, attended the scene close to the roundabout which links Guyhirn and Wisbech at around 1pm.
An East of England Ambulance Service spokesman said: 'We were called to Wisbech to reports of a man who had collapsed and was unconscious.
'When we arrived we found a male, believed to be in his 50s, who was in a serious condition.
'He was taken to Queen Elizabeth Hospital in King's Lynn, where he was in a critical condition.'
A Cambridgeshire police spokesman said: 'We were called today by the ambulance service at 12.54pm with reports of a man having been stung by a wasp and going into cardiac arrest on the A47, approximately one mile from the Wisbech roundabout, heading towards Guyhirn.'
