Plaid Cymru leader Leanne Wood has written to First Minister Carwyn Jones citing 'concerns' over standards of NHS care in Wales.
Her letter comes amidst growing calls for a major inquiry into the state of the Welsh NHS, similar to the high-profile Keogh inquiry carried out in England - the results of which were published earlier this month.
The Welsh Government said: 'We confirm a letter has been received. We will respond to it via the usual process in due course.'
