Ah right, so I think I've found the detail here: http://www.legislation.gov.uk/uksi/2012/1547/made
...which is...(2) Paragraph 1(d) of Schedule 1 to these Regulations will come into force on 16th October 2012
So essentially British dual citizens will be considered on the 2006 regulations until that date?(d)in the definition of “EEA national” after “a national of an EEA State” insert “who is not also a United Kingdom national”
