A fresh batch of international talent will descend on England's Zurich Premiership after a flurry of summer transfer activity.

Wasps have signalled their intent to improve on last season by tempting former Wales and Lions scrum-half Rob Howley to London.

But champions Leicester have also added to their squad, with French prop Franck Tournaire one of the new arrivals at Welford Road.

The southern hemisphere contingent has also swelled with the arrivals of Wallaby Graeme Bond, Springboks Andre Vos and Thinus Delport, and All Black Bruce Reihana.

Here BBC Sport Online gives a full run-down on the main arrivals and departures at each of the 12 Zurich Premiership clubs.
