Agreement has been reached over the participation of Italian teams in the Pro12 league.

The Italian Rugby Federation, Federazione Italiana Rugby (FIR) has agreed to ensure the particpation of two sides in the Pro12 competition for the next four years.

There had been concerns that Zebre and Treviso, the two Italian sides currently partcipating in teh Pro12, would leave the competition at the end of the season.

Last month, Treviso released a statement indicating their intention to leave the Pro12, citing uncertainty about its future.

However, a joint statement from the sport’s governing bodies and the Pro12 said a “constructive meeting” had taken place between the FIR and the Celtic Rugby Unions (the Scottish and Welsh unions and the  IRFU).

“The meeting was successful and an agreement was reached for FIR to join Celtic Rugby as an equal partner from July 1st, 2014,” the statement said. “The terms of participation of two Italian teams were agreed upon.

“Under the new agreement, FIR will ensure the participation of two Italian teams for the next four years in the competition which is currently known as the RaboDirect PRO12.”

The agreement between FIR, SRU, WRU and IRFU will be officially signed in due course, the statement said.
