In addition to claiming she drives almost 1,000 miles a week, Janet Anderson also claimed £1,700 in rail expenses over the same 12-month period.
“Ms Anderson needs to come clean on these quite unbelievable expenses,” said Roddy Graham, Leasedrive VELO commercial director.
“If the expenses claim is justified then she must take a long hard look at the safety of all road users, as we can only assume that she is driving while very tired.”
He said the MP “poses a threat to herself and other road users due to her obvious tiredness and fatigue at the wheel”.
When the House of Commons is sitting, which it does for 276 days a year, MPs can work more than 80 hours a week, with days starting before 9am and debates often running until 10pm. The safety implications of an employee working a seven-day week including many nights, and then driving some 1,000 miles would have fleet managers seriously concerned.
According to research in the British Medical Journal, 20% of collisions are caused by sleeplessness.
More than 300 people in the UK a year are killed as a result of drivers falling asleep at the wheel.
In response, Ms Anderson said: “I confirm that I frequently drive between Westminster and my constituency, though I am trying to travel more often by public transport in future.”
