The announcement came as Theresa May said that her government was “determined to reduce the number of immigrants coming into the country by thousands”.
In his response, Mohadi said that the southern African country had no problem taking back its nationals but it needed to check them to ensure they were truly Zimbabweans.
“… We said we want to vet them before they leave the UK. We want to know whether or not they are Zimbabweans or if they are not fugitives who had run away from justice,” Mohadi was quoted as saying.
Around 20 000 British citizens lived in Zimbabwe while at least 112 000 Zimbabweans lived in Britain, according to reports.
Relations between the two countries went rocky under ex-president Robert Mugabe, particularly over the controversial land reform programme.
