A flight to take asylum seekers from the UK to Rwanda next Tuesday has been allowed to go ahead by the High Court.
Campaigners failed in an initial legal bid to halt the removals to the east African country, but have confirmed they will take the case to the Court of Appeal on Monday.
Under the policy, some of those entering the UK illegally will be flown to Rwanda to apply for asylum there.
About 31 people have been told they may be on the first flight.
There will be a full judicial review, where the High Court will hear a challenge to the policy as a whole, before the end of July, it heard.
In his decision, the judge Mr Justice Swift accepted there was a "material public interest" in Home Secretary Priti Patel being able to carry out her policies.
