Jim Hamilton, the departing Gloucester captain and Scotland internationalist, is among the latest additions to the Barbarians squad for their games against England and the British & Irish Lions.

The Baa-Baas play England at Twickenham on May 26, then head to Hong Kong for an appointment with Warren Gatland's Lions six days later.

Former England Under-20 forward Sam Jones has also been added and will be joined by his Wasps colleague Marco Wentzel, while other additions include Perpignan-based Wales international back James Hook and fellow Welshmen Dwayne Peel and Matthew Rees.

Players from 10 different countries are now represented, including Hong Kong sevens captain Rowan Varty, USA wing Takudzwa Ngwenya and Samoa scrum-half Kahn Fotuali'i.

"Our selection process has taken several months and is still not quite complete," said Derek Quinnell, the Barbarians team manager. "Over the next week or so, we will be monitoring the domestic play-off matches in Europe and the various national squads for the summer tours. We expect to add other names in the near future."
