There are systems that do give local accountability to an MP. For instance you could have single transferrable vote for constituency MPs and then 'county' MPs based on the support proportions across the county. The set up is a bit Pittesque, but the voting system would be much fairer (either than the current system or Pitt!).

The issue we have with our current system is that a party with only 34% has unfettered power, only restricted by the courts and Lords (for now). A change won't happen anyway, as both main parties stand to lose in a change of voting system.
