Where I live (Brazil) there has been widespread debate about state funding of political parties. It happens at the moment (I think something like 400mi USD is invested in it), but the issue with it is that it has prompted a load of small, socially inexpressive political parties to be founded to get money from that fund.

Debate also spins around prohibition of donations from companies or from donations over 2000 reais or something by a person (around 950 USD). Some would argue that company interests are valid and that prohibiting that would just generate that sort of funding illegally; others would say this sort of company funding is the root of a very corrupt system. This should be one of the main points of a try at political reform in the next four years.

Not necessarily is "being a parliament" a problem -- after all, parties are together for a reason. Except they are usually ideological in most countries (liberals, social-democrats, socialists), and not a group of people that got into parties to get, as noted by the article, in the party most convenient for the district where you come from.
