In a nutshell - BIG uncertainty !
It is over 100 years since a national election has been won by a party other than the Conservatives and Labour.
This election proved to me that people doubt that
> Labour can manage the economy
> The Conservatives can read the mood of the country (although Cameron has held a European reform position for a while so has read the mood of folks better than most)
> The Liberal Democrats can keep promises
and UKIP doesn't have bench strength.
The UK is still running a very large current account deficit - about £20bn over the quarter.
Its going to be a bumpy ride up to the election in May 2015. That said Cameron could emerge as a strong leader and Britain may be seen as an increasingly attractive place to invest.
