Sky Sports will be sharing live coverage of Guinness Premiership rugby union matches with Irish pay-TV broadcaster Setanta from late 2010. The two companies have signed a three-year Â£54m deal that will more than double the number of Guinness Premiership games broadcast live. Today's deal, which will come into effect from the 2010-11 season, represents a 45% increase in TV rights revenue, according to the competition's organiser, Premier Rugby. The number of live televised Premiership games will more than double from 33 under the current deal to 69 each season under the new agreement. Irish pay-TV company Setanta Sports will broadcast 43 live Guinness Premiership games, including one semi-final, each season. Sky Sports will broadcast 26 live Guinness Premiership games including a semi-final. "The substantial increase in income and coverage for the Guinness Premiership is fantastic news for our clubs, their supporters and sponsors and is a reflection of the growing attraction of club rugby," said Mark McCafferty, the Premier Rugby chief executive. "We are delighted to continue our relationship with Sky Sports and look forward to working with Setanta Sports on delivering more matches from the Guinness Premiership than ever before," McCafferty added. In addition to the live rights Premier Rugby, which manages the rights for domestic Premiership rugby, has reached deals for highlights, broadband and mobile but has not yet released details. However, McCafferty said there will be a free-to-air highlights show. Guinness Premiership highlights are currently broadcast on ITV4. The current broadcast arrangements have another season and a half to run and will conclude at the end of the 2009-10 season in May 2010. Details here.
