Leeds Teaching Hospitals NHS Trust has netted itself almost £80,000 in car parking fines over the last year, according to new figures.
The data was collected by the Press Association, which asked some 120 NHS trusts across England to give figures on parking charges and fines under the Freedom of Information Act - 89 provided responses.
Data on parking fines, provided by 27 trusts, showed they made £2,300,208 in fines over a four year period - with Leeds earning the most from fining patients, visitors and staff on hospital grounds, at £78,595.
In 2015/16 alone, £635,387 was made from fining patients, visitors and staff on hospital grounds.
The figures also revealed that NHS hospitals across England have made more than £120 million in car park charges over the last year.
Katherine Murphy, chief executive of the Patients Association, said it was unfair that hospital parking in Wales and Scotland was largely free but that patients in England were made to pay.
A spokesperson for Leeds Teaching Hospitals NHS Trust said it was one of the largest NHS trusts in the country treating around 1.5 million patients every year.
Overall it had over 5,000 car parking spaces across six hospital sites - and that with over 1.6 million vehicles on site each year, the figures about income from parking fines should be seen in that context.
