There are European elections coming up, and I would expect a large turnout following the expenses scandals of the past few weeks.

There are some MPs who have effectively committed fraud by taking money when they were not allowed.
And there are also MPs who have taken money that you might not agree with, but they have stayed within the rules. I feel sorry for MPs on that. Anyone would take money if they were offered it, so it's hard to judge them badly for using the expenses system they were given. Many asked for advice from those in charge. Everyone in the country has been examining them and they haven't had the chance to defend themselves as they would have done if the expenses system had been investigated internally.
If you want to change the system, then fine, but don't vote for a silly party as a protest - because they could get into power! It's proportional representation in the European elections, so they don't need many votes to get an MEP.
