tons of ash from all the foot-and-mouth pyres across the North-East is heading to Teesside.

And there is no guarantee it will be leaving, because a final site for the ash has not been agreed.

Last week, it was revealed that ash from the burial site at Widdrington, Northumberland, would be stored temporarily at the Freightliner depot at Wilton, near Redcar, before going to a landfill site in the South-East.

It has now emerged that a final destination for the ash has not been agreed and no one knows how long the ash - which is being stored in special containers - will be on Teesside.

It is still unclear whether the material will be leaving by rail or road.

Redcar MP Vera Baird expressed concern that the potentially carcinogenic material was being stored in proximity to schools and houses at Grangetown, Middlesbrough.
