London Irish have confirmed the signing of Australia international James O'Connor until the end of the season.

The Aviva Premiership side were widely expected to announce the capture of the Wallabies back, who will be looking to use the move as a means of forcing his way back into the national squad before the 2015 World Cup.

O'Connor is expected to make his debut for the Exiles in Sunday's clash against Northampton.

"Having decided that I needed a change from both a personal and playing point of view, I spoke to clubs in Japan and France and concluded that the best way forward for my development was to move to England," said the 23-year-old.

"Given that I've left my support network back in Australia, London Irish offered me an environment that I felt comfortable with."
