Politics never had a particularly good name, but after the expenses scandal, it really has become a profession to be ashamed of. Only the Lib Dems have the courage to offer the kind of fundamental changes that will fix our broken politics.
The problems that plague our system of representation are numerous and wide ranging, but I think we should start by looking at how expensive parliament actually is. As well as the fact that their expenses were/are opaque and almost totally unregulated, I think there are also far too many MPs (they can't even all fit in the house at once!) Add to that the fact that our democratic system is corrupt, since we allow all sorts of exceptions so that foreign nationals and big companies can donate money to political campaigns so they get taken more seriously that British voters, and unfair, where we discount some voters choices if they choose the "wrong" party in their area. And on top of all that, peoples' local services are run from large unaccountable bodies like Police Force Headquarters and Primary Care Trusts. There are other problems too, but I think these are the main ones that make politics so inaccessible and unfair.
The Liberal Democrats are proposing a large set of changes to tackle all of these problems. To start with, we would cut the number of MPs by 150 and make expenses transparent and fair (taking care not to discourage people with families from standing for Parliament,) cutting the cost of Parliament significantly in the process. I think it's really important that any changes to the way expenses work don't stop people from all backgrounds standing for Parliament, and with the Lib Dems commitment to equality I trust them to make an unfair and expensive system into a fair one that is good value.
We would tighten up the laws for funding election campaigns to keep big money and corrupt donors out of political altogether. We would also reform the way elections are run; so that you can make a genuine choice on election day and vote for the party you want to represent you, rather than forcing you to make a tactical decision. One of the things that I think government is supposed to do is take power away from the rich and give it to everyone equally. The Lib Dems would change the campaign finance law so that this is really the case both on election day, and every other day.
We would give local people control over their local services, by putting management of the police and NHS in the hands of locally elected officials rather than Whitehall departments, and give people the right to sack their MP if they break the rules. I think people should be in charge of their own local services as this both makes them more empowered when trying to solve problems with them, and allows councils to try different things to more quickly find best practise; and that goes for MPs as well as NHS administrators and police chiefs.
I don't think Labour or the Conservatives will ever offer change on this scale; the status quo is too convenient for them. I saw this when Labour came out for a referendum on the "alternative vote" system; it is one under which the Labour vote goes further while the Tory one is held back; another politically motivated constitutional reform proposal. Only the Liberal Democrats are offering the chance for a new, different politics, as far as I can see. In the words of Nick Clegg, "Another whitewash is unacceptable, we need permanent change to make politics clean, fair and local."
