What is the point of Plaid in government?

On the day when Labour drove a coach and horses though the devolution settlement in Wales what is the response from the supposed Party of Wales?

Well according to their web site at 1 minute to midnight the only thing they have to say today is a press release from one of thier AMs in a cross party role challenging Wales to produce role models that challenge size zero and hence reduce the prevalence of eating disorders.

Now don't get me wrong I work hard to give my 6 year old daughter positive role models and applaud this initiative put wasn't something more important going on today?

Something about the secretary of state having a right under legislation to block the will of the Assembly in Cardiff over housing policy

Isn't this the very thing that Plaid told us wouldn't happen. Sure they may have kept their powder dry for the Welsh Language LCO but now they not only have to fight Labour on that one they have to fight the precedent they themselves as part of government have set by accepting this draconian oversight on this order.

So I ask myself again what is the point of Plaid in government? The more I see of it the answer seems to be none
