Week one draws to an end with David Cameron just on course to stay in power, according to the polls.

The ebbs and flows of this General Election campaign have been brutal and instant. Much more immediate than anything anyone has ever had to grapple with in British politics.

But his attempts to woo the C-suite community fell flat in many commentators’ eyes, with the FT’s influential Lombard column writing it off altogether.

Former deputy PM John Prescott accused them of being “tax dodgers” and even the savvy and usually pro-business Chuka Umunna weighed into the assault.
So in the space of three days Labour’s bid to win over the business community has descended into rancour and bitterness.

So power could flow to Labour and the Scots Nats.
This would raise immense questions about Britain’s voting system.
Not many would support the notion that the UK is governed by a party which came second in a General Election and propped up by a minority party intent on breaking up the country.
This political uncertainty is reflected in the markets.
Sterling has weakened against both the euro and the dollar in recent weeks.
With the shape of the next government likely to remain unclear, there may be further turbulence as the election approaches.
