Drivers who take disabled people's parking spaces have been branded selfish by a Labour backbench MSP.
Right by the store entrance - a temptation for many drivers
Duncan McNeil, who has called for "space invaders" to be fined, claims one in five bays in supermarkets and other private places are hijacked.
Offenders at present can be prosecuted on a public road, but not when private parking is involved.
Mr McNeil is supported by fellow-MSP Johann Lamont, who demanded a "comprehensive awareness" campaign.
He said: "Disabled drivers from across my constituency express to me
their frustration, not just at the bone-idle and selfish 'space invaders' who
abuse disabled parking space, but at the apparent reluctance of car park owners
to enforce their own parking policy."
The MSP for Greenock and Inverclyde added: "If we cannot make the present system work, perhaps it is time to go beyond appealing to people's better nature and start appealing to their pockets."
Ms Lamont wants a probe into rules governing the abuse of parking bays outside the homes of disabled drivers.
"The accounts of intimidation and neighbourhood conflict which some of my most vulnerable constituents relate to me are, frankly, deplorable," she
The MSP for Glasgow Pollock added: "Their only crime is to be sufficiently infirm to require a disabled parking space outside their homes."
Campaign group Baywatch monitored parking at more than 800 stores owned by the 'big four' supermarkets - Sainsbury's, Asda, Safeway and Tesco in January.
The results showed that almost 21% of disabled parking spaces were occupied by cars without a blue parking badge - which compares with 18.5% at the same time last year.
