FRANKFURT- The euro zone economy may have shrunk by less than the 13% forecast by the European Central Bank in the three months to the end of June, the ECB Vice President Luis de Guindos said on Wednesday.

"In light of the data we've received in the last days and weeks, it may be a bit less negative than the 13% we forecast," de Guindos said.

"The latest data has been relatively more optimistic than we were expecting just a few weeks ago."
