Britain's new interior minister vowed Monday to sort out an immigration scandal shaking the government, saying that as the child of immigrants he was angered by the mistreatment of long-term residents from the Caribbean. "It immediately impacted me".
Meanwhile, the European Parliament's Brexit co-ordinator Guy Verhofstadt called for Mr Javid to "go to all lengths to dispel any fears that what was visited on the Windrush generation will not be repeated in respect of EU citizens living in the United Kingdom". His parents moved to Britain from Pakistan in the 1960s and he said the Windrush crisis hit home for him.
Over the weekend, he told the Sunday Telegraph the Windrush scandal felt "very personal".
The new Home Secretary was Secretary of State for Housing, Communities and Local Government from 2016 to 2018 and served as Business Secretary under former Prime Minister David Cameron.
International Development Secretary Penny Mordaunt adds to her duties Rudd's other brief as minister for women and equalities.
Theresa May has defended targets for the removal of illegal immigrants as she confirmed the practice was in place when she was home secretary.
Her clampdown on illegal immigration, that began as a bid to identify those without papers, scooped up many elderly people from the Windrush generation - named after the ship that brought the first group of migrants from the West Indies in 1948.
With less than a year to go before Britain exits the European Union - a decision voters made in part to stem immigration - the government is confronting a scandal over its treatment of migrants, both legal and illegal.
"The immigration arm of the Home Office has been using local targets for internal performance management".
"I feel it is necessary to do so because I inadvertently misled the Home Affairs Select Committee over targets for removal of illegal immigrants during their questions on Windrush".
Rudd's departure deals a further blow to the embattled Prime Minister's leadership, after a misjudged election past year aimed at "strengthening her hand" in Brexit negotiations backfired spectacularly when her Conservative party lost its parliamentary majority.
Rudd's resignation after the Guardian revealed that in a leaked 2017 letter to May, Rudd had told the Prime Minister of her intention to increase deportations by 10 per cent, seemingly at odds with her denials that she was aware of deportation targets. The prime minister doesn't have a majority in the United Kingdom parliament and is struggling with Brexit negotiations.
Rudd's resignation comes four months after another close ally and her then most senior minister, Damian Green, was forced out of his job for lying about whether he knew pornography had been found on computers in his parliamentary office.
