The Home Office has earmarked at least £700m to manage the arrival of migrants on small boats until 2030, according to previously unnoticed commercial plans.
Officials published the projections online last week, as Home Secretary James Cleverly flew to Rwanda to sign a new treaty to “stop the boats”.
The plans predict the Channel crossings could continue up to 2034.
Under the plans, commercial partners would run extensive services at “permanent” facilities.
Potential bidders will get full details if they agree to keep them secret.
A Home Office spokesperson said it would be “inappropriate to comment” on an ongoing procurement project.
But the publicly-available information, on the government’s contracts website, shows that the Home Office wants at least one major partner to help run two large facilities in Kent until at least 2030 – and potentially to 2034.
