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.

Drivers at P&O Trans European, who deliver petrol and fuel supplies on contract to Shell, announced on Wednesday that they would be staging the 72-hour stoppage after rejecting a 2.5% pay rise.

Negotiations have been taking place between P&O and the Transport and General Workers' Union (TGWU) since January in an attempt to find a settlement.

The drivers want a substantial pay rise to reflect what they say is the dangerous and responsible nature of their job.

'Low pay'

However P&O has stood firm and last week, the drivers voted overwhelmingly in favour of strike action.

Ron Webb, TGWU national secretary, said: "Union members at P&O have suffered for years with low pay increases.

"Average industry wages are good, P&O and Shell report huge profits, so why are they so reluctant to pay our members fair wages?

"The vote of 80% in favour of strike action should send a strong and clear signal that P&O should resume meaningful talks to resolve this dispute."

'Remain hopeful'

The strike is due to be held from 19 July to 22 July but Shell is hoping the action can be averted.

A spokesman for the company said: "We remain hopeful that a settlement can be reached between P&O and the TGWU.

"We are working closely with P&O to reach an agreement that is fair and acceptable for all parties."

Shell operates 1,100 petrol stations across the UK.

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.
