Downing Street has insisted David Cameron followed all the “proper processes” after it emerged his Nepalese nanny has been granted British citizenship.
A spokeswoman refused to confirm whether the Prime Minister had written to the authorities as an employer supporting Gita Lima’s application.
But she said the nanny was “someone who has come here and works hard”.
Questions were raised about Mr Cameron’s use of foreign domestic help after a Minister deplored the effects of the “metropolitan elite” using cheap migrant workers.
Home Office Minister James Brokenshire said the wealthy had been the main winners from Britain’s openness to labour from abroad, because they had to pay less for tradesmen and services.
“For too long, the benefits of immigration went to employers who wanted an easy supply of cheap labour, or to the wealthy metropolitan elite who wanted cheap tradesmen and services, but not to the ordinary, hard-working people of this country,” the Tory Minister said in a speech to the Demos think-tank yesterday.
Mr Cameron has employed Ms Lima for several years since recruiting her through from Kalayaan, a charity that helps immigrants to escape abusive bosses.
She took a temporary leave of absence in 2012, during which an Australian nanny filled in.
No 10 initially stonewalled questions on whether it was appropriate for Mr Cameron to use foreign nannies, before disclosing that Ms Lima had been granted UK citizenship. The spokeswoman said: “I think you can expect that the Prime Minister would follow the normal process in the right way.”
