Besides pointless questions at PMQs which never get answered anyway?
From Douglas Carswell's blog, quoting Alan Clark:
"Commenting on a Council of Ministers meeting arranged by UKREP in 1983, Clark writes:
"A succession of meetings, but no possibility of getting anything changed - not at my level anyway. Everything is fixed by officials in advance. Ministers shaking hands are just window dressing".
After twenty something years, it seems nothing has changed. Even after this year's election ....."
Carswell and Hannan carry the hopes of all Eurosceptics, being as they have the 'ear of the media' - in Carswell's case 'the ear of Parliament' - to the extent if either of them sneeze, the media report it.
So a question - and to paraphrase - Are they both content to take 'Cameron's Shilling' - or will they actually do something?
