The oil industry has revealed that oil supplies in Britain will run out in the next 24 hours.
Protests remain in place at terminals and refineries across the country.
The numbers outside the Shell Oil refinery in Cheshire have swelled from 40 to 100 people. About 20 protesters were outside the gates of the Manchester Fuels Terminal where their presence is estimated to have halted more than 400 tanker-loads of fuel since action started on Saturday night. More than 500,000 litres of fuel should have left the depot in the Trafford Park industrial estate over the past three days. The storage facility, which holds 22 million litres of fuel, provides Esso, Texaco and Elf customers with supplies over an area stretching from the Scottish Borders, through the northwest of England and into the Midlands and North Wales. On the south coast at the Esso Fawley Refinery in Hythe, near Southampton, up to 20 protesters and 12 vehicles were still outside the plant's entrance.
