I swear I would kick the next 'journalist' who complains about 'unelected prime ministers'. There is no such thing. You do not vote for prime ministers, you vote for members of parliament to represent your constituency. Whether David Cameron (whose party did not win I might add), Nick Clegg or whoever runs Labour next becomes prime minister, they are still 'unelected'.
Fucking hell, you would think political editors would know such thing, but like everything else run by the mainstream (mainly Tory) media they are just ignorant dolts.
