Here's what the election results would have looked like under STV

We already know how the election results would look under a strictly proportional system.

Now political analyst Lewis Baston has detailed how they could look under Single Transferable Vote, a slightly more complex form of PR used in Scottish local elections and in Northern Ireland. Under it, voters rank candidates in order of preference with constituencies returning three or four MPs.

While interesting, there is a caveat - as Baston puts it, modelling different electoral systems is "at best an approximate art."

Under the model, this is how the country would be divided - all the colours on the map below are arbitrary to show the difference between constituencies:

Baston writes writes:

When I first posted the headline number on Twitter, someone asked me ‘what sort of government would that produce’? A fair question. My guess would be a Conservative minority with occasional support from the Ulster Unionists (DUP and UUP), UKIP and the Lib Dems, and a measure of passive toleration from the SNP. It might be an easier show to keep on the road than a triumphalist yet divided Conservative majority, but that is even more speculative than any of these calculations.

Here are how different regions would look under Baston's model. Scroll down the chart to see the differences.
