The British government’s contentious plan to send some asylum-seekers on a one-way trip to Rwanda could cost nearly half a billion pounds, or about 0 million, plus hundreds of thousands for each deported person, a report said Friday. The Conservative government had earlier only revealed a 290 million pound (6 million) commitment, so the new figures opened the plan to wider scrutiny from critics. “These figures reveal the extortionate bill the taxpayer will have to pay the Rwandan government for an unworkable and inhumane scheme that will not deter people seeking protection on our shores," said Enver Solomon, chief executive of the Refugee Council.
