BBC: Former prime minister Theresa May has criticised the government's plan to send some asylum seekers to Rwanda.
Mrs May told the Commons she did not support the policy due to her concerns over whether it met standards on "legality, practicality and efficacy".
Home Secretary Priti Patel said the scheme would be "a major blow to people smugglers" and would stop people dying on dangerous routes to the UK.
The policy has been criticised by charities and opposition parties.
Mrs May, who also served as home secretary overseeing the UK's immigration policy between 2010 and 2016, asked if the trial scheme would lead to an increase in trafficking of women and children - after reports that only single men making illegal crossings to the UK would be sent to Rwanda.
Under the scheme - announced last week - people deemed to have entered the UK unlawfully will be flown to the African country, where they would be processed, and if successful, would have long-term accommodation in the African country.
Responding to a statement on migration by Ms Patel, Mrs May said: "From what I have heard and seen so far of this policy, I do not support the removal to Rwanda policy on the grounds of legality, practicality and efficacy.
"If it is the case that families will not be broken up, does she not believe and where is her evidence that this will not simply lead to an increase in the trafficking of women and children?" » | BBC | Tuesday, April 19, 2022
