Unsurprisingly, the government is taking the threat of a fuel strike  seriously. David Cameron will chair a meeting of Cobra this afternoon and the cabinet has been briefed on plans to train the army to stand in for striking drivers. Yesterday a No 10 spokeswoman hinted that the public should begin stockpiling fuel:
It is important that people look at their contingency plans because, should there be a dispute, which is something obviously we want to avoid, then disruption is inevitable.
Cameron is clearly determined to prevent a repeat of the 2000 fuel protests when pumps ran dry across the country. And he has every political incentive to do so. The last drivers' strike saw the Conservatives take the lead over Labour for the first time since the 1997 election. As the graph below shows, in the wake of the action, a 15-point Labour lead became a four-point Tory lead. With Cameron's party already haemorrhaging support  over the Budget and the "cash for access" scandal, a drivers' strike could further sour the mood.
There is, of course, one big difference between this dispute and that of 2000. The latter was triggered by the Blair government's refusal to cut fuel duty, while the current disagreement was sparked by the oil companies' failure to impose minimum safety standards. Unite members in five of the seven firms involved have voted for strike action. In a piece for the Guardian, the union's general secretary Len McCluskey  writes of "a categorical failure of business to behave responsibly".
But if supplies run low over the Easter weekend [the likely date for the strike], Cameron and co are unlikely to avoid at least some of the blame. All of which explains the government's sudden urgency.
