Perpignan forward Luke Narraway has agreed a two-year deal with London Irish.
The 30-year-old, who has won seven caps for England, will join the Aviva Premiership club at the end of the season.
"There has been a lot of positive news to come out of London Irish over the last six months, not least with the announcement of the new board of directors and the move to a new state of the art training ground," Narraway told Irish's official website.
"I'm excited with the direction the club are heading and I'm looking forward to being a part of their plans."
Narraway joined Perpignan from Gloucester Rugby in 2012 following a nine-year spell in the West Country.
