MP Daniel Kawczynski in inquiry plea over Wrexham ambulance queues
An MP has called for an investigation into the impact of delays at Welsh hospitals on the NHS in England.
Queues at Wrexham Maelor Hospital have seen some paramedics taking patients to Royal Shrewsbury Hospital, putting pressure on beds there.
Shrewsbury and Atcham Conservative MP Daniel Kawczynski called for a Department of Health investigation.
Welsh Assembly Member for Wrexham Lesley Griffiths said an extra £40m was being allocated to the NHS in Wales.
Figures released last autumn showed 15% of ambulances coming from Shropshire were being delayed for an hour or more at Wrexham.
Wrexham Maelor is the local hospital for people living in north Shropshire.
Mr Kawczynski said: "I'm calling for an investigation by the Department of Health and the Welsh department as to what the impact is on constituents in border areas suffering from divergence [of service]."
Shropshire Clinical Commissioning Group accountable officer Caron Morton said: "We had two patients picked up in Shropshire, Shropshire residents who out of choice wanted to go to Wrexham but waited in excess of four hours in the back of ambulances.
"(That) in essence means between four and five hours of ambulance time lost, but also not the type of patient experience that we would want for our patients in Shropshire."
The Welsh government said it was a matter for the local health board and the ambulance service.
