'Panic buying' at petrol stations
Queues formed at some petrol stations as demand for fuel shot up after ministers called for people to top up in case of a tanker drivers' strike.
The government has rejected retailer claims that their advice has caused "panic buying".
Anticipating a strike they describe as "completely wrong", ministers had called for motorists to keep their cars "topped up" but urged people not to queue.
The BBC's deputy political editor James Landale reports.
