LONDON, June 5 (Reuters) - The dollar recovered from last week's seven-month lows on Monday, edging up against the euro and yen, but still looking exposed to any renewed optimism from a European Central Bank policy meeting this week.
Sterling, on a rollercoaster ride driven by diverging opinion polls ahead of Thursday's national election, also recovered after a van and knife attack on pedestrians in central London on Saturday drove a brief drop in early Asian trade.
Services data from the data are the main set-piece of the European morning on Monday, but dealers say the week should be dominated by the UK election and the ECB meeting, eyed for signs of the bank turning towards tighter policy later this year.
Coming at a time when political risk in Europe has eased, U.S. economic data has worsened and expectations for more rises in Federal Reserve rates have fallen, that prospect pushed the euro to a seven-month high on Friday.
"Overall we think the risks are skewed towards a more cautious stance (from the ECB) than the market is expecting," said Barclays strategist Nick Sgouropoulos, pointing to more downbeat messages sent by other major central banks in recent weeks.
"It would be a very big message for the ECB to go ahead of everybody else. They want to be very cautious about how they change the wording of their statement. We don't think the euro goes further (up) from here."
The euro fell just over 0.1 percent to $1.1270, still very close to Friday's high of $1.1285. The dollar was also 0.1 percent stronger at 110.48 yen.
Other moves among the G10 group of major developed world currencies, however, kept the dollar index almost flat compared to Friday's close at 96.756.
The pound's trade-weighted value has fallen by 3 percent in just under 4 weeks as Prime Minister Theresa May's bid for a landslide electoral victory that would strengthen her hand in talks on leaving the European Union ran into trouble.
It was not immediately clear how the events on Saturday would impact the election, though the issue of security has been thrust to the forefront of the campaign after the London Bridge and Manchester attacks.
Polls have given widely varying results, but some indicate the election could be close, possibly throwing Britain into political deadlock just days before formal Brexit talks with the European Union are due to begin on June 19.
"The pound has made an impressive recovery in early trading after a torrid weekend," said City Index analyst Kathleen Brooks.
"Although the Tory lead has been eroded, if the FT's poll of polls is correct then it would suggest that the Conservatives will win this election, but maybe not by such a comfortable majority as was expected a month ago."
Sterling traded almost flat compared to Friday's close at $1.2885 and 0.1 percent higher at 87.14 pence per euro by 0906 GMT.
