I really hope not. Coalition rule hasn't done much for Brighton and Hove council. Thankfully I live out of the area, so I am not experiencing the mess first hand, but it's very clear that divergent policies and a lack of single vision from one party does not work.
But BHCC hasn't been a coalition - the opposition parties stood aside and allowed the Greens to run the council as a minority administration.
At government level the same could have happened - i.e. the Tories could have run a minority government - but the Lib Dems decided they would help form a majority coalition government.
For what it's worth, true coalition would always by my preference as it helps keep both parties in power in check to an extent.
