What changed on Thomson?

The Prime Minister Julia Gillard, yesterday said a ''dark cloud'' hung over Parliament and she had asked Craig Thomson to leave the Labor Party.

But even after the Fair Work Australia report was released, she continued to support him:

JULIA GILLARD: I have expressed my full confidence in the Member for Dobell and I continue to do so

So what has changed? Is Gillard aware of imminent charges against Mr Thomson over his alleged misuse of union member's money?
