LONDON, Nov 17: The dollar weakened against the euro on Monday after world leaders failed to deliver specific measures to boost the global economy, dealers said, but predicted the euro’s rally would not last.

In late London trade, the euro rose to $1.2739 from $1.2591 reached late in New York on Friday.
