LONDON, June 3: A computer failure that briefly grounded all aircraft in Britain at the peak morning time caused airport chaos on Thursday and raised further questions about the state of the country's transport infrastructure.

The computer crash that disrupted some of Europe's busiest airspace added to pressure on the government amid talk of a consumer backlash over soaring petrol prices and with strikes looming in the crumbling national rail network.

Prime Minister Tony Blair's Labour government blamed a lack of investment in the country's transport system by previous administrations. "Over decades, successive governments did not spend enough on the infrastructure" Transport Secretary Alistair Darling told BBC radio. -Reuters
