I am perplexed as why the UK election outcome of a minority government is characterized as a cause of concern. I am a citizen of parliamentary democracy very similar to the UK system and I have lived under many instances of minority govt and also majority gvmt. I will tell you from experience that minority gvmt is the best form of gvmt as the possibility of a failed vote of confidence in the gvmt at any time keeps all the MPs on their toes! The result is fair and balanced legislation gets passed. Very little corruption happens, there is little to no boondoggle funds for bridges to nowhere. The individual MPs actually get a lot more power to exercise in the gvmt as every vote in the house counts; as opposed to a majority gvmt where the prime minister's office rules the party like a dictator.
All this being said about the benefits of minority gvmt, there are cases like in Italy where the complete fracturing of parties into hundreds of sub-parties represented in the gvmt, results in deadlock (too many chiefs, and not enough indians). In the case of the UK, there are only a handful of parties so the Italian problem will not exist.
