UK refineries are located at major ports so import of crude and export of product is largely market driven.

Nah, Stanlow certainly isn't on a major port and is the second biggest refinery.

Stanlow, how does it get it's oil if not near a major port?

Dunno, pipe? I do know that oil tankers do not come any where near Stanlow (and I live about 10 miles away). I do have an oil pipe going through my land but it's a feed going south not to Stanlow.

Edit: just checked and it's piped in from Tranmere.

its not just the bookies

the fact is clean up from an oil spill as big as this is virtually impossible, oil is still present in the sands around the exxon valdeez crash and the wetlands in the gulf are considered a more valuable and delicate environment

bp having publicly signed up to foot the bill could end up paying to complete a never ending task
