Norman Tebbit, a former Conservative minister, once asked in relation to cricket, whether Pakistanis born in England supported the England cricket team when they played Pakistan. He used what was to be called “the Norman Tebbbit cricket test” to question the patriotism of Pakistanis and other minorities born in the UK.

Tebbit would have been outraged if he came to Wembley on 2 June this year when England hosted Nigeria in a pre-World Cup friendly. The overwhelming majority of Nigerians and Brits of Nigerian heritage in the stands were rooting for the Super Eagles of Nigeria. But for many Nigerians in the UK, it goes beyond supporting your country of birth or country of your parents’ birth against England. Many, possibly the majority, favour an Anyone But England aka ABEG approach during international competitions.
