Wasps have signed experienced second row forward Ed O'Donoghue.
The 29-year-old has previously played for Leinster, Ulster, Queensland Reds, Worcester and Northampton.
He grew up in Brisbane to Irish parents and joined Northampton before moving to Worcester and then played 13 times for the Reds in the 2007 Super 14.
He represented Ulster 45 times during two years at Ravenhill and earned international recognition with Ireland 'A' in 2009.
O'Donoghue said: "Wasps is a great club with a lot of history.
"With a relatively new group of players and coaching staff, this is a great opportunity for me to be part of a club moving in a good direction."
London Wasps director of rugby Dai Young added: "Ed has got a lot of experience in some quality rugby environments and he will be a good addition to the squad."
