Durham Wildcats have been confirmed as new additons to the British Basketball League for the 2011/12 season.
The club, who played in the National Division One last term, have won two promotions in the last three seasons.
"We are delighted to welcome the Durham Wildcats to the BBL," said BBL chairman Paul Blake.
"Their community ethos aligns perfectly to the BBL's own strategy, and they have all the key ingredients to build a successful franchise."
Durham Wildcats senior basketball side is one of a network of mens' and womens' teams within the club that was formed in 2005.
"'Sport in County Durham is built on successful partnerships and we are no different," said Wildcats chairman Quentin Sloper.
"Durham County Council, Durham University and the Community Sports Partnership have all played significant roles in getting the club this far.
"Our long-term success will without question be partially determined by how successful we are in developing our existing partnerships and how we establish and grow new relationships with local and regional partners.
"We are determined to deliver a rounded product, from grassroots to performance level, a product that the county can be proud of and that people feel part of."
Durham's near-neighbours Newcastle Eagles are one of the division's most successful clubs, and the addition of the Wildcats doubles the north east's quota in the BBL.
