The British currency strengthened for a second straight day versus its two major counterparts, the U.S. Dollar and the Euro, after a report showed bigger expansion of the U.K. services than economists expected. Sterling added 0.2% to $1.5151 on Tuesday following an 0.5% advance the day before, after it touched the lowest level in more than 2 years on March 1. It also jumped 0.2% to 86.04 pence per euro.
