London:  More than a third of Britons still have feelings for their first love, and one in four has got back in touch thanks to Facebook, reveals a new study.

Six out of 10 people regularly think about their old flame, the study found.

Nearly four out of 10 admit to still carrying a torch for their teenage sweetheart, according to a poll for The Best Of Me, a film about a couple who give first love a second chance.

“Many look back more fondly at a first love than other failed relationships, leaving many wondering what might have been and, possibly, what could still be,” a spokesman for the film was quoted as saying.

Twelve percent of those who stay in touch with the first love consider them a good friend, although a third admits their partner does not know.
