The cost of Rishi Sunak's troubled Rwanda asylum scheme could soar to half a billion pounds, plus hundreds of thousands more for each deportee, an investigation by the public spending watchdog has found.The Home Office has so far refused to say how much more money, on top of the £290 million already confirmed, the UK has agreed to pay Kigali under the stalled plan, but a National Audit Office report has revealed millions more in spending including £11,000 for each migrant's plane ticket.Critics said the "staggering figures" reveal "the extortionate bill the taxpayer will have to pay the Rwandan government for an unworkable and inhumane scheme" and "the national scandal the Tories have been trying to hide".
