Irish rugby bosses have pledged to pump an extra €4million into provincial and club rugby every year.

The Irish Rugby Football Union has generated a multi-million euro surplus for the second year running, resulting in a significant cash boost for the domestic game.

The IRFU, which on Friday saw Martin O'Sullivan from the UL Bohemians club in Limerick enrolled as its 128th president during its annual council meeting at the Aviva Stadium, reported a surplus in excess of €8.7m owing to ticket sales, new broadcasting deals and Ireland's two straight RBS 6 Nations titles.

Last year the IRFU posted a surplus of €7.3m, leaving the organisation in rude health ahead of next month's Rugby World Cup.

"There are significant risks facing the union," said honorary treasurer Tom Grace.

"Including economic uncertainty, the free-to-air issue and the relative financial strength of our partners and competitors in international and provincial rugby.

"For the second year in a row the success of the national team in the RBS 6 Nations has boosted the level of prize money secured from the tournament.

"The strong support of the national team at the Aviva Stadium remains a vital source of revenue for the Union and contributes massively to the IRFU's ability to provide funding to all levels of the game in Ireland."

The positive financial picture still comes amid a backdrop of the IRFU continuing structured repayments of the six-year loan taken in 2013.

The IRFU reported a €26m loss in projected earnings from the sale of five and 10-year tickets in their 2012/13 accounts.
