New Welsh Secretary Stephen Crabb turns to one of the items at the top of his in-tray today -the row between the Welsh and UK governments over who pays for the electrification of the Valley lines. Ministers in Cardiff Bay say Mr Crabb's predecessors, Cheryl Gillan and David Jones, were quick to claim the credit for the giving the multi-million pound project the go ahead, so there's no way that the bill should be passed on.
Today Mr Crabb will hold talks with this cabinet colleague, the Transport Secretary, Patrick McLoughlin. The Transport Department argues that as the Welsh Government manages the Wales and Borders rail franchise, it should be responsible for repaying the cost. That would mean either funding a bigger subsidy or putting up the fares.
Only yesterday, the Prime Minister defended what he saw as a done deal but ITV news understands that there might at least be a concession over how quickly the money needs to be repaid. A senior Welsh Government source was also optimistic that the dispute could soon be settled.
The new Welsh Secretary Stephen Crabb says there's no competition between him and Welsh Conservative leader Andrew RT Davies.
There had been disputes between Mr Davies and the previous Welsh Secretary over which man should be considered leader of the Tories in Wales.
Mr Crabb says they both have different jobs to do.

Downing Street has confirmed that Vale of Glamorgan MP Alun Cairns is the new junior minister at the Wales Office. He takes over the role from the new Secretary of State, Stephen Crabb.
As was the case when Mr Crabb held the post, Mr Cairns will also be a government whip and do the Wales Office job part time. Both men are Conservative MPs, with the Liberal Democrat peer Baroness Randerson completing the Wales Office ministerial team.
First Minister Carwyn Jones has told AMs that the Welsh Government does "very much welcome what we hope will be a new approach" from Stephen Crabb.
He said Welsh ministers had found the new Secretary of State "pragmatic and reasonable" to deal with during his time as a junior minister at the Wales Office.
Mr Jones added that he hoped the Welsh Government and the UK Department of Transport can move forward on Valleys rail electrification with the help of the new Secretary of State. There's disagreement between the two governments on which of them should pay for the project.

He's called on Mr Crabb to "break free from the ceaseless negativity that has characterised his predecessors’ attitude to Wales and the achievements of the Welsh Government". Mr Smith has also drawn attention to the new Secretary of State's past doubts about devolution.
