Public Expenditure Minister Brendan Howlin has said it is likely that there will have to be a supplementary budget to deal with cost over-runs in the Department of Health.

The revelation came during the minister’s response to Dáil questions from Sinn Fein’s Mary Lou McDonald on the issue.

Taoiseach Enda Kenny has repeatedly denied that there is to be any supplementary estimate for the department, but Mr Howlin said he would be meeting Health Minister James Reilly to discuss his department’s finances.

Minister Howlin said it was now likely there would have to be extra cash.

Earlier this month, the HSE estimated the year end deficit in Health could reach €500m.
