A SUPERMARKET worker has been awarded more than £13,000 after injuring her back when she tripped on uneven flooring at her store.

Marilyn Clarey, 47, sued Wm Morrison, claiming the company was responsible for the accident.

But the supermarket group has been granted indemnity from paying the award of £13,561.

Judge Guy Whitburn ruled that the construction company renovating the store was responsible for the accident.

Mrs Clarey had been stacking shelves during a night shift at the store in Bishop Auckland, County Durham, when she fell.

Construction workers had repaired tiling on the floor of the store earlier in the evening.

But Mrs Clarey claimed that stones were stuck to glue on the tiles, forming lumps on the floor.

She said she tripped on the stones and dropped to her knees before falling backwards onto her spine.

Mrs Clarey was immediately taken to hospital and the stones filed down.

Newcastle County Court heard that the accident happened in December 1996, at about 2am, as workers from Estill Cooper Construction renovated the store.

Mrs Clarey, from Toft Hill in Bishop Auckland, had been pushing a large plastic container when she fell.
