The cricket test, also known as the Tebbit test, was a controversial phrase coined in April 1990 by the British Conservative politician Norman Tebbit in reference to the perceived lack of loyalty of immigrants and their children from South Asia and the Caribbean to the England cricket team. Tebbit suggested that those immigrants who support their native countries rather than England at the sport of cricket are not significantly integrated into the United Kingdom. 
Post-war Britain experienced mass migration from the cricket playing countries of the West Indies and South Asia. Ever since the issue of assimilation and multiculturalism has been a controversial issue in British politics.
Tebbit, in an interview with the Los Angeles Times, said: "A large proportion of Britain's Asian population fail to pass the cricket test. Which side do they cheer for? It's an interesting test. Are you still harking back to where you came from or where you are?"
Tebbit told Woodrow Wyatt in 1991 that he did not think certain immigrant communities would assimilate "because some of them insist on sticking to their own culture, like the Muslims in Bradford and so forth, and they are extremely dangerous".
The phrase 'cricket test' and the associated loyalty concepts received a lot of media attention for many months after Tebbit's statement, and have been widely discussed and argued over ever since.
