News that Downing Street has written to the First Minister offering face to face talks with the Prime Minister over Brexit was broken by our Political Editor on Twitter.
A similar offer has been made to the Scottish First Minister, Nicola Sturgeon. She and Carwyn Jones have been co-operating closely, with both First Ministers saying they will do all they can to block the EU withdrawal bill unless plans to transfer Brussels' powers in devolved areas to Westminster are dropped.
The First Minister has accused the UK government of a power-grab, arguing that EU powers in areas such as agriculture and economic development should come straight to Cardiff Bay. The UK government has said it will respect the convention that Westminster must ask the Welsh Assembly and Scottish Parliament for agreement before passing a law affecting a devolved matter. That's raised the prospect of Carwyn Jones and Nicola Sturgeon having a veto over the Brexit legislation if agreement can't be reached.
