A new opinion poll shows that exactly half of those surveyed no longer trust the Taoiseach to run the country after hearing more of his evidence to the Mahon Tribunal.

However, the 'Red C' poll  for today's Sunday Business Post shows support for Fianna Fáil has increased slightly while support for Fine Gael is down.

The poll also indicates that support for the Lisbon Treaty is outweighing opposition by two to one.
