The Rulers of Britain imported the Third-world hordes to dilute and dissolve the political power of native Britons. Corrupt Pakis pose no threat to the Powers That Be. The question then becomes, "Who rules Britain?" because its obviously not the British people.
No, they didn’t.
The first mass immigration into the UK started in 1948 and continued for a decade, blacks and Asians and HK Chinese.
As I have just said to another poster, it was a labour shortage due to WW2 that caused the need for immigrants. BTW, it was the CONSERVATIVE govt was in power in most of these years, inc Churchill. 1951-64.
There was no problem with the Muslim (Pakistani) communities in the UK until the Satanic Verses hoo-ha in 1989. Like the Sikhs and Hindus. The racial problems in the UK had been with the black Caribbean community.
Until then, the Muslims had been quiet, peaceful, hardworking communities, which is why 1989 genuinely shocked the British public.
