Campaigners who want Leeds Children's heart surgery to continue in the city and for services not to be transferred to Newcastle believe the decison against them was 'biased".
They have obtained NHS spending figures which they claim shows millions of pounds were being invested in the North East in the years before by the very group trusted to carry out the national review.
The decision was made earlier this year to end children's heart surgery in Leeds and develop existing services in Newcastle - but was that influenced by a pattern of spending on specialised services in the years before that campaigners say was at expense of other regions?
It is claimed Yorkshire and Humber received just £3.49 per person - compared with the North East which reeived £13.36 per head. The figures on total spending were obtained by Leeds West MP Rachel Reeves.
Tomorrow a meeting of 15 local authorities is expected to formally ask for the decision to be referred to the Health Secretary. The acting director of the National Specialised Commisisoning team today said;
"The regional cost-per head analysis put forward is fundamentally flawed as it does not reflect that hospitals provide specialist services for patients from across the United Kingdom with very rare and complex conditions. "
Next week Campaigners are hoping to take their fight to the High Court **as they embark on a legal challenge to stop services being lost in Leeds.
