Yes. That's a big issue every election, but is likely to be an even bigger pain point this time round. Both Labour and the Lib Dems are now calling for electoral reform (some kind of proportional representation instead of first past the post).
People will say anything you want to keep power/money, etc.
That said PR is still a better system for representing minorities and forming governments - so personally I favour a hybrid model, possibly with a different house for each system.
I'm not a BNP supporter by a long stretch but, if they get a significant proportion of the vote then IMO they should get representation in parliament.
I actually considered not voting, our ward is a pretty much foregone conclusion, proportional representation (in preference to first-past-the-post) makes all votes count and would encourage people to vote with their conscience rather than tactically.
