The Fianna Fáil leader believes that a government must be formed soon.
Formal talks have taken place between Fianna Fáil and Fine Gael, however, there have been calls for a national unity government to overcome the obstacles facing the country in the short-term.
The Dáil is unable to pass legislation until a new government is formed, as outgoing Taoiseach Leo Varadkar cannot elect the 11 members required to complete the Seanad.
Micheál Martin disagrees with Labour’s suggestion that a regulation change could allow the Seanad to meet with the full complement of members.
Speaking on Kerry Today, the Fianna Fáil leader said he believes a national unity government wouldn’t work.
