Yeah, I read about that. Seems bonkers, they are not required to be there. If they want to bring their whole family home from whatever holiday they are on to attend this voluntary event, they should pay for it themselves.
Oh come on bud, you expect poor MP's to pay out of their own pocket for stuff like this, they are already surviving on that breadline MP's wage of £65.000 a year and anything they can scrap from their second/ third £100,000 jobs sitting on boards here and there, and of course that little bit extra they can scrap from their pittance of a expense form.
Come on, have a heart, poor wee buggers.
