The First Minister has joined forces with the leader of Plaid Cymru to present the UK Government with an alternative plan for leaving the European Union.
The two leaders will put forward their proposals in a White Paper that they'll publish together in Westminster tomorrow but they've set out their principles in a joint article for the Sunday Times today.
Carwyn Jones and Leanne Wood describe their blueprint as 'a comprehensive, credible plan based on solid evidence that centres on Wales’s priorities.'
It will include:
Continued 'participation' in the single market
A 'sensible' approach to immigration with 'more effective control' and 'a clearer link' to employment in the UK
EU citizens already here should be allowed to stay; 'no ifs not buts.'
Wales should 'not lose a penny of its current funding as a result of leaving the EU'
There's an alternative view, however, being put forward by the Welsh Conservative leader Andrew RT Davies.
Also writing in today's Sunday Times, he sets out the opportunities for Wales of a clean break from the EU, praising the Prime Minister's 'clear plan' and criticising Carwyn Jone' Welsh Government as 'an impotent First Minister' turning a deaf ear to the referendum result.
Carwyn Jones and Leanne Wood say their plan differs from that set out by Theresa May by continuing to insist that the UK remains involved in the European Single Market.
The Welsh Labour leader and Plaid Cymru leader will stand together when they present their White Paper in Westminster tomorrow even though their two parties aren't in a formal coalition.
I understand that the proposals were negotiated through the liaison committee set up as part of the compact they reached after Labour failed to win a majority of seats in the Senedd in last May's election.
In fact, this Brexit plan is the product of three parties because the sole Liberal Democrat in the Assembly, Kirsty Williams, is already part of the Welsh Government.
