Interesting to note that Michael Noonan has effectively (and rightly) called Brian Lenihan a liar over his postponement of the injection of a further €10 billion into the banks until after the election.
Noonan said he did not believe the decision had been approved by the Cabinet, ECB or the IMF. This suggests that Lenihan was acting as a rogue minister outside of Cabinet and made the decision purely on the grounds that it was good for Fianna Fail.
This sort of behaviour is only possible in a seriously dysfuntional state.
