Today's intervention by Carwyn Jones follows protests from parents in north Wales. Campaigners have argued against moving services that are currently provided in three hospitals in north Wales transferred to Arrowe Park on the Wirral.
Those fighting the plans have warned that plans to treat babies more than 16-weeks premature at a single intensive care neonatal service at Arrowe Park, on the Wirral, would leave relatives with too far to travel.
Earlier this month the First Minister announced that he would personally decide whether to call in the controversial plans.
He said he would take personal responsibility because the previous Health Minister Lesley Griffiths's Wrexham constituency would be directly affected by the plans.
