I have just spoken to a source at Unite who tells me the union has again written to the Government to ask them to 'stop contaminating the environment'.
I am told they have been discussing the issue of health and safety with ministers for two years. They believe the Government's been politicising what is actually an industrial issue. They hope the letter will calm things down. They also stressed they do not want a strike.
Motorists have been ignoring calls not to panic buy fuel prompting shortages and queues at petrol forecourts across the country.
Petrol operators around the country have attempted to weather the latest fuel crisis, by means of hiking up prices in some areas.
