All languages are endogenous to UK - as is English. It's not like we have English, Welsh, Scots, Gaelic but fcukin French has been imposed on all of them because of few French migrants in London. Ask the English if they would accept that.Here in England, the Welsh speak Welsh, the Scottish and Irish speak Gaelic. But all speak English band this is a binding force.
Similar examples of a single dominant language can be found in pretty much all countries of the world.
So spare us from your bigotry.
This is exactly what has happened in Pakistan.
By making Urdu official language of Pakistan media, PTV etc were hijacked by one set of speakers and Indian culture, music, fashion has been foisted on Pakistan. Just look at PTV it is dominated by one angle, mostly Indian.
