C&C Group has confirmed that its Magners Irish cider brand has extended its sponsorship of the Magners League rugby competition in the UK.

The Ireland-based company said today (24 March) that the Magners League tie-up, which is midway through its third season, will be extended to at least May 2011.

Financial details behind the agreement with league organisers Celtic Rugby were not disclosed.

"Our relationship with Celtic Rugby has been productive and rewarding over the last three years and we are delighted to be extending our partnership," said Stephen Kent, marketing director at Wm Magner.

"Since the first year of sponsorship the stature of the Magners League has increased significantly; the next two seasons will mark a new stage in the development of the tournament, particularly with the introduction of season ending play-offs and we are excited about the prospect of being involved in this process."

Magners involvement in rugby began in 2003 with the sponsorship of Edinburgh Rugby and in 2005 extended to London Wasps, although Magners announced last month that its sponsorship of Wasps will cease at the end of this season. The company said that it will continue to invest in its ongoing development by "engaging rugby fans, the teams and media, and working closely with Celtic Rugby on the inaugural play-offs in 2009/10".
