An angry MP is calling for clarity over delays to improve the A14 six months after sections slumped alarmingly and police connected its design to a serious road accident.

David Ruffley, MP for Bury St Edmunds, has demanded clear answers from roads bosses on two outstanding safety inquiries on the A14 relating to subsidence and aquaplaning.

He said road users were 'still in the dark' over issues relating to sinking road surfaces and potentially dangerous puddles on the £12million Rookery Crossroads stretch at Rougham near Bury which opened in 2006.

Mr Ruffley said:

'I am not satisfied. I want to know what the problem is and I want a full update. If it is subsidence then they should be able to tell us what the scale of it is and what they are going to do about it.

'The Highways Agency seems determined to the keep the member for Rougham and everyone else in the dark. And following a thoroughly inadequate reply from the Highways Agency Chief Executive I have asked for an urgent update on how it might affect Suffolk's busiest road.'
