UK Rwanda asylum-seeker flight cancelled after European ruling

The number of those due to be put on the flight had dwindled from an original 130 to seven on Tuesday and finally none thanks to a last-minute ruling from the European Court of Human Rights (ECHR).

British Home Secretary Priti Patel said she was disappointed that "legal challenge and last-minute claims" meant the plane did not take off but vowed to pursue the heavily criticised policy.

“We will not be deterred," she said in a statement.

"Our legal team are reviewing every decision made on this flight and preparation for the next flight begins now."

The grounding was thanks to an ECHR ruling that at least one of the asylum seekers should stay in Britain as there were no guarantees for his legal future in Rwanda, which earlier agreed to take in a number of refugees bound for the United Kingdom in a controversial deal with London.

Patel called the ECHR intervention "very surprising" and vowed that "many of those removed from this flight will be placed on the next".

The flight cancellation is an embarrassment for Johnson's Conservative government after Foreign Secretary Liz Truss insisted the Kigali-bound plane would leave no matter how many people were on board.

But the ECHR issued an urgent interim measure to prevent the deportation of an Iraqi man booked on the flight as he may have been tortured and his asylum application was not completed.

The Strasbourg-based court said the expulsion should wait until British courts have taken a final decision on the legality of the policy, set for July.
