Independent Galway West TD Noel Grealish has confirmed that he has withdrawn his support for the Government.
The move follows a meeting with the HSE West yesterday over budget cuts.
Deputy Grealish has been threatening to withdraw his support for months and called for a General Election earlier this week.
Speaking to Galway Bay Fm, Deputy Grealish said he was available to meet the Taoiseach or Health Minister Mary Harney to discuss the matter.
