Timeline of Rwanda asylum plan leading up to the Supreme Court’s ruling

The Supreme Court judgment on the Government’s plans to removal asylum seekers to Rwanda comes more than 18 months after they were first announced.

Legal battles have meant no migrants have been sent to the East African nation under the policy, which the UK’s highest court has concluded is unlawful.

Here is how events leading up to the ruling from the UK’s highest court on Wednesday have unfolded since the Rwanda plan was unveiled:

– 2022
