A LORRY driver whose articulated truck ploughed into cars queuing to get off a motorway killing an Isleham father-of-four has been jailed for 16 months.

A project to widen two stretches of the UK's busiest motorway could have wasted £1bn of public money, MPs have said.

The Highways Agency gave poor cost estimates for the M25 scheme and did not look at possible cheaper alternatives, the public accounts committee found.

The MPs also questioned why it had taken nine years to sign a contract with a private company to do the work.

But the agency said the project was progressing on time and under budget.
