Organisers TransAction 2007 welcomed around 300 vehicles to an A40 protest, with a further 100 reported in Wales, according to Times Online. "We are not faceless multinational companies - we are small and medium family companies built up over generations with hard work and determination," read a letter from the group to Gordon Brown.

Meanwhile, French president Nicholas Sarkozy has stated that a Europe-wide cut in VAT would bring down the cost of fuel across the continent About 65 vehicles converged in Park Lane in protest at a 30% rise in diesel pump prices in 12 months. The organisers presented a coffin to the Houses of Parliament to represent hundreds of haulage firms they claim have gone bankrupt as a result.

It follows a 48-hour strike at Grangemouth oil refinery in Scotland in a dispute over pension changes. Tuesday's protest has been organised by TransAction 2007, one of the groups behind fuel protests in 2000 which caused 90% of petrol stations to run dry. The convoy started off in Kent and headed up M2 motorway into the capital.

Organisers said fuel for a typical articulated lorry now costs up to £1,000 per week. The problem was exacerbated by foreign hauliers who arrive in the UK "full to the brim with cheaper fuel", spokesman Mike Presneill said. "Our industry is the lifeblood of the UK economy," he added.

"Fuel is rising on a daily basis. It is now at levels that are bankrupting hundreds of small and medium-sized haulage companies." First to arrive was driver Mick Clifton, 37, who works for the JS Cook company based at Moulton Chapel in Lincolnshire. He said: "The price of fuel at the moment is ridiculous. We just don't know whether our jobs are going to be safe.

"If Gordon Brown doesn't do something about this soon he'll be out of office." The Road Haulage Association's chief executive Roger King has urged the government to abandon plans to raise fuel duty by 2p next October. He said: "We support a peaceful and legal protest and that is what this is. We think such an exercise helps underscore the real feelings hauliers have." Protesters have also handed a letter summarising their grievances to the Houses of Parliament, together with a copy of the 2005 Burns Inquiry. The independent inquiry into the effect of fuel taxation found that the level of diesel duty in the UK was higher than the average EU rate.

The Road Haulage Association represents over 10,000 transport companies that operate within the hire-and-reward sector of the UK based logistics sector. The association provides dedicated advice, information and business services tailored to the needs of its membership. Another vital role is that of negotiator. Not just in high profile discussions with Government on national issues; but also through regular contact with local planning committees, regional transport groups and, of course, the European Commission.
