How important is transparency for politicians?
Just weeks before the general election, there are yet more claims about the behaviour of MPs, this time in relation to their activities outside Parliament and lobbying.
A BBC investigation has found that more than 20 MPs broke rules on declaring hospitality in questions or debates after accepting free overseas trips from foreign governments.
Meanwhile, three former ministers have been suspended from the Labour party over allegations that they were willing to lobby for cash.
Stephen Byers, Patricia Hewitt and Geoff Hoon have denied wrongdoing after they were secretly filmed as part of an investigation by the Sunday Times and the Channel 4's Dispatches.
But should there be tougher limits for lobbying and campaigning in government? And should MPs' activities outside Parliament be more closely regulated? Following last year's expenses scandals, do these latest stories affect your trust in politicians and your view of the forthcoming election campaign?
