The election deepened the serious domestic divisions & the UK's difficulties regarding upcoming EU negotiations. 

The 2 leading Parties, Conservative and Labour, each suffer deep internal divisions over a wide range of important public policy issues & experience major leadership problems that will not be easily resolved. Neither is currently equipped to govern the UK because of problems that extend well beyond not having a majority in the Commons).

A Conservative Government, reliant on the Northern Ireland DUP, will be more reactionary and intransigent on domestic social issues and EU negotiations. The DUP is almost as anti-EU as UKIP except that it demands that the Irish Republic border remains open after the UK leaves the EU (good luck with that).

Debilitating political paralysis & intransigence coupled with splits & defections from both leading Parties are unfortunately likely possibilities.
