The new House of Lords definition of a 'main home' (update)

Further to my piece about the disgusting ruling that the House of Lords definition of a 'main home' is now one where the noble Lord spends at least one night a month during the time Parliament is sitting. I see on Letters From A Tory that Liberal Democrat MP Norman Baker, has commented :

"If you want to see what whitewashed ermine looks like, this is it. This ruling has more holes in it than a colander."

Excellent sound-bite...
