A Birmingham MP has claimed that patients could be turned away from doctor's surgeries because they're too fat.
John Hemming, Liberal Democrat MP for Yardley, urged the Prime Minister to stop health trusts rejecting overweight patients.
It follows the decision of two health trusts to ration healthcare for patients who refuse to lose weight.
Mr Hemming said he feared the same could happen in Birmingham.
In a Commons exchange, he pointed out that Arnold Schwarzenegger, the superstar actor who became governor of California, would be considered overweight.
And Mr Hemming admitted he had a body-mass index of more than 30, which meant he was officially overweight.
Mr Hemming said: "A growing number of primary care trusts are refusing to put patients on waiting lists unless they have a body mass index under 30, and that is to save money, reduce deficits and ration healthcare.
"Does the Prime Minister believe this is an acceptable way of rationing access to healthcare?"
Mr Blair replied by saying he should be grateful that under a Labour Government nobody in Yardley had to wait more than six months for treatment.
Health trusts in North Lincolnshire are refusing to supply some operations to overweight patients, and NHS trusts in Suffolk are limiting hip and knee surgery for obese patients.
