Electoral Load-balancing

I can't help but think that I'd not get away with load-balancing of resources assuming an equal prioritisation of requests as the British political system allows with votes. No doubt the Tories got the most seats and should rightly be charged with forming a government. However,  based on raw votes the distribution is unequal and the system is weighted in favour of the main two parties...  and the emergent SNP! The table below is based on UK elections result data from The Guardian assuming you get the number of seats relative to the number of votes cast.

Suppressing minorities or mitigating extremities? Or a bit of both... It should not though be for the incumbents; and the system is a product of them, to decide. Perhaps our electoral system could do with an updated load-balancing strategy.
