Crypto-English
Etymology is obvious.
Noun:
A person who claims to be of Scottish, Irish, or Welsh descent but who fervently defends (shills for) England. Usually this is a result of them sharing English ancestry or being majority English. In other words, "Crypto-English". Compare "no true scotsman".
Singular is "Crypto-Englishman", plural is "Crypto-English", also "Crypto-Englishmen". "Crypto-Angloid" can also be used if you're feeling a tad bit ruder than usual.
