The British government has vowed to explore other avenues to organize more flights to deport asylum-seekers from the UK to Rwanda after a last-minute legal setback which saw a court judgment grounding the first plane due to take off under a controversial deal with the East African country.

The flight which was suppose to take around 30 illegal migrants, was scheduled to leave on Tuesday night but was put on hold after a ruling by the European Human Rights Court (EHRC), which issued a last-minute injunction to stop the deportation of of migrants on board.

But despite the setback, the Boris Johnson government says there is no going back in the plan to deport the migrants who came to the UK illegally through the English Channel.

UK Home Secretary, Priti Patel, while reacting to the last minute injunction that stopped the take off of the flight on Wednesday, said “preparation for the next flight begins now” despite legal rulings that none of the migrants earmarked for deportation could be sent to the East African country.

She insisted that under the deal signed in April between Britain and Rwanda, the UK government is not relentiing in going ahead with the plans to send “migrants who arrive in the UK as stowaways or in small boats to Rwanda”, where their asylum claims will be processed.

As part of the deal which is with £120 million to Rwanda, successfully profiled migrants will stay in the African country, rather than return to Britain.

Johnson’s government has also repeatedly said the plan is a legitimate way to protect lives and thwart the criminal gangs that send migrants on risky journeys across the English Channel and must be carried through after Britain had already paid Rwanda upfront for the deal.

UK courts had last week, refused to ground the first flight but the number due to be aboard was whittled down by appeals and legal challenges.

But the European Court, an international tribunal supported by 46 countries including the UK, ruled late Tuesday that an Iraqi man due to be on the plane shouldn’t fly, saying he faced “a real risk of irreversible harm,” which allowed the final few migrants on the plane to win a reprieve.

A full trial of the legality of the UK government plan is due to be heard in the British courts by the end of July.
