The number of adult patients on trolleys in hospital emergency departments is rising again.

Figures this morning showed that there were 420 patients waiting around the country.

The Irish Nurses and Midwives Organisation said Our Lady of Lourdes Hospital had 51 patients waiting, the largest number at a single hospital.

It was followed by University Hospital Galway, which had 44 patients waiting, and Dublin's Beaumont Hospital, which had 33.

Responding to the figures, Fianna Fáil leader Micheál Martin claimed there was a lack of control over the health service, with waiting times increasing and no indication of who is in charge.
