There's just been a very interesting interview with John Dixon, Chair of Plaid Cymru, on the Politics Show Wales.
At a conference of Plaid members yesterday, the party voted to continue to oppose top-up fees in Wales. This is out of line with Labour's position and that's the position that's likely to be followed through.
So one might ask what is the point of having Plaid in government at all?
John Dixon did not deny that there was a void between Plaid policy and government action and said that compromise was an important part of being in government.
So where should Plaid be drawing the line?
