In Portcullis House I presume? You'd have thought for the amount it added to the National Debt (and all those chimneys) they could have done proper smoke extraction.

I actually think it's not right to enforce no smoking in things like consulting rooms. What if you do have some old dear who's all nervous and wound up (I know, nicotine makes them worse, but they don't realise that). It's presumably quite a big ordeal for some coming down to see their MP.
