2006–07 National Division One
The 2006–07 National Division One was the 20th full season of rugby union within the second tier of the English league system, currently known as the RFU Championship. This season saw the league increased from 14 to 16 teams with new teams including Leeds Tykes (relegated from the 2005-06 Guinness Premiership), as well as Moseley and Waterloo who were promoted from 2005–06 National Division Two. Other changes saw Exeter Chiefs move from the County Ground to Sandy Park, a modern stadium with room for further expansion, Nottingham moved from Ireland Avenue to groundshare with Notts County at the much larger Meadow Lane and finally Cornish Pirates moved from their temporary ground at Kenwyn in Truro to the larger (and more permanent) Recreation Ground owned by Camborne RFC.
