In his speech, Wales Office minister David Jones is expected to blame Labour for 'messing up the Welsh economy.'
But he'll say the UK Government is prepared to work closely with ministers in Cardiff Bay despite political differences and calls for a 'mature response' from the Welsh Government.
Here's an extract from what he plans to say:
Wales is a proud and ancient nation. As a Welshman, I consider it nothing short of a national disgrace that it continues to need bail-outs from Europe alongside impoverished Balkan nations.
Cheryl and I have high ambitions for Wales. We want all of Wales to show the dynamism that is displayed here at Glynd?r OpTIC.
We want Wales to reach for the stars, too. And we want the Welsh Government to work closely with us to that end.'
