"Initially, polls showed the Tories with as much as a 20 percentage point lead over the seemingly hapless Labour Party.  The polls closed considerably following the latest Tory reversal (on the extent of elderly responsibility for their own health care costs).  This appeared to weigh on sterling last week when it suffered its largest weekly decline in six months (-1.8%).  

As many as six polls were reported over the weekend that showed the Tories are still set to win the coming weekend election.  All the results gave the Tories a wider lead than the YouGov poll before the weekend, which put the lead at five percentage points. On average, the weekend polls gave the Tories an average of a 10-point margin. Sterling was the strongest of the major currencies, gaining about 0.3% against the dollar and euro."
