Carwyn Jones has been criticised by opponents and by supporters within the Labour party for being distracted by constitutional obsessions. That's why in his speech he'll set out the practical reasons why he believes the Welsh Government needs strengthened powers:
As First Minister, my job is to deliver my Programme of Government for the people of Wales. Everything I say about constitutional reform needs to be set in this context.
We are striving to use the powers we have to create jobs, support the economy and sustain public services in an economic and fiscal context which is extremely challenging. This means using our legislative and executive powers to full effect.
It also means standing up for Wales when the decisions of the UK Government are in our view ill-judged or plain wrong, as in the area of welfare reform.
