In a speech this evening, the First Minister is expected to outline two big changes he wants to see to the way devolution works. During a lecture to the London School of Economics he's due to reveal what his government will tell the Silk Commission which is looking into the Assembly's powers.
He's expected to call for a move to what's known as a 'reserved powers model' of devolution, similar to the arrangement for Scotland. This would set out what the Welsh Government CAN'T do rather than setting out what it CAN do as is currently the case.
Carwyn Jones will also call for a Welsh judge to be appointed to the Supreme Court. With legislation from Wales being examined by the Supreme court to see if it's lawful, the First Minister is expected to say that it's unfair that Wales isn't represented there.
