SHADOW health secretary Andy Burnham is to mount a fact-finding mission about Dewsbury District Hospital.
He was briefed this week by Labour parliamentary candidate for Batley and Spen Jo Cox on plans to cut some services there.
The Staincliffe site faces losing full A&E and maternity care in changes that will see older buildings demolished.
Mrs Cox highlighted concerns about the readiness of proposed community care services that form part of the reorganisation.
She said: "Cutting hospital services before the whole Care Closer to Home agenda is geared up is a recipe for disaster."
A date for Mr Burnham's visit to Batley and Spen is not yet confirmed. He was health secretary in the last Labour government.
Mr Burnham said a future Labour administration would repeal the controversial 2012 Health and Social Care Act.
Campaigners believe the bill opens the door for private companies to take over NHS services.
Mr Burnham said on the health and social care act: “If we leave things as they are, the NHS as we have known it for 66 years will not survive."
