Supplies to Shell filling stations look set to be disrupted after tanker drivers across the UK announced they are to hold a three-day strike.
The strike is due to be held from 19 July to 22 July but Shell is hoping the action can be averted.
The walkout involves staff from 13 fuel depots at Buncefield in Hemel Hempstead, Hertfordshire; Shell Haven at Thurrock, Essex; Avonmouth in Bristol; Plymouth; Hythe in Southampton; Haverfordwest; Killinghome and Kingsbury in the Midlands; Stanlow in Cheshire; Grangemouth; Aberdeen and Inverness.
