Afraid not. DNA showing 100% Brigante, Dumnonii, Catuvellauni, Trinovante, Corieltauvi, Cantiaci or Pict blood is necessary (a combination might be acceptable🤔). More seriously, imo anyone who is English by birth or naturalisation, and identifies themself as English is English irrespective of their colour. As I stated previously, the introduction of the use of the phrase, 'Ethnic English' just serves to drive a false divide between white and non-white Englishmen and is simply a pseudo-intellectual attempt to justify racism.
