It seems to be only black immigrants who are questioned (Man in UK for 57 years loses job for lack of ID papers, 10 April). I was a Commonwealth immigrant in 1965 – from Australia. Have any Aussies, New Zealanders, Canadians, or white South Africans been threatened with deportation?

• What a delight that Country diary is tail-ended by Clifford Harper’s charming vignettes (I suspect in scraperboard).
