British Prime Minister Rishi Sunak will station Home Office officials in Rwanda as he tries to see off an escalating Conservative Party rebellion over his small boats policy.

Axar.az reports the prime minister is expected to unveil a new treaty with Rwanda this week in response to a court ruling that the scheme to deport illegal migrants to the country is unlawful.

The decision to deploy British officials to support the African nation’s asylum system will be seen as vindication for Suella Braverman, the recently deposed home secretary, who pressed for the move while in government.

It comes as Conservative MPs on the party’s right warned their leader that he is facing an electoral “catastrophe” including the Tories being reduced to a “rump” of 60 seats if the prime minister fails to tackle illegal migration.

One backbencher said they believed “dozens” of letters of no confidence in Sunak had already been submitted to the 1922 Committee of Tory MPs.
