Andrews grilled on firefighters promises

Victorian Premier Daniel Andrews has again denied the existence of secret deals with the state's powerful firefighters union secretary Peter Marshall or that he's sought legal advice on claims to the contrary.

Mr Andrews was grilled on the controversial and ongoing firefighters pay deal during a budget estimates hearing on Tuesday.

Mr Marshall previously said Mr Andrews had made promises to him at the last election and threatened to expose them but on Tuesday the Premier said "the only commitments that have been made by our government are those which are on the public record".
