“Our thoughts are with the woman's family at this desperately difficult time.

“I am re-appealing for anyone who saw either the Transit van or the camper van before the collision to please make contact with police.

“The roads were not as busy as they would normally be, but we do believe that a number of people will have witnessed this collision.

“Anybody who was driving in the area, can I ask you to please check your dash-cam footage and contact police if it has captured anything that can assist with this investigation."
