What will happen to the Salisbury Convention under the Coalition Government?

The constitutional and parliamentary questions continue to arise on the back of the new arrangements we have in place with the Coalition Government.

I still don't have an answer to my last question (Will Conservative and Lib Dem MPs refer to each other as "honourable friends"?) so here's another poser, which I raised during my interview on tonight's Westminster Hour:

What will happen to the Salisbury Convention under the Coalition Government?

That is of course the convention which states that the House of Lords will not vote down the governing party's manifesto commitments when put before the Upper House.

But what will happen now that both governing parties' manifestos have been cherry-picked?

Will peers accept that anything in the finalised Coalition Agreement should not be voted down? But then how does that fit with the fact that this programme was never put in its entirety to the electorate?
