Sterling rose against 12 of its 16 major peers amid speculation the 47 billion-pound ($70 billion) deal, one of the largest in the oil and gas industry for at least a decade, may prompt more mergers.

The pound rose 0.9 percent to $1.4936 at 4:19 p.m. London time, the biggest increase since March 20. Sterling appreciated 1 percent to 72.32 pence per euro. The FTSE 100 Index of shares fell 0.3 percent after climbing as much as 0.7 percent.
