The city's three MPs all voted against the controversial Rwanda immigration Bill.

It will finally become law after a parliamentary showdown ended late into Monday night.

Rishi Sunak's plans to send some asylum seekers to Africa have met fierce criticism but the Bill passed  when the Lords dropped their opposition.

Mr Sunak said in a statement "nothing will stand in our way" now of getting flights off the ground but the scheme could still be held up by challenges in the courts.

Brighton Pavilion MP Caroline Lucas, Hove MP Peter Kyle and Kemp Town MP Lloyd Russell-Moyle all voted against it.

Mr Kyle said: "The Rwanda scheme is an extortionately expensive gimmick. It's not a serious plan to tackle dangerous boat crossings and no one in the country really believes it will work.

“Yet the government stubbornly ploughs on - spending more than half a billion pounds on it. They should be putting that money into boosting our border security instead - that is Labour’s practical plan."

Mr Russell-Moyle said: “The Rwanda Bill is a chaotic failure. The Rwanda scheme will not only fail to tackle criminal gangs or protect border security but it will cost the taxpayer £570 million, working out at nearly £2 million per asylum seeker.”

Sussex Tories including Peter Bottomley, MP for Worthing West and Tim Loughton, MP for East Worthing and Shoreham, voted for the Bill which prohibits asylum seekers from applying to return to the UK and aims to deter people from entering the UK illegally on small boats across the English Channel.

Others who voted in favour were Conservatives Gillian Keegan, MP for Chichester; Nick Gibb, Bognor and Littlehampton; Caroline Ansell, Eastbourne; Sally-Ann Hart, Hastings and Rye; Andrew Griffith, Arundel and South Downs; Mims Davies, Mid Sussex; Maria Caulfield, Lewes and Polegate; Nus Ghani, Wealden; Huw Merriman, Bexhill and Battle; Jeremy Quin, Horsham.

Crawley Conservative MP Henry Smith's vote was unrecorded.

The Prime Minister said the first flights would depart in ten to 12 weeks.

The cost of the Rwanda plan will be at least £370 million, according to the National Audit Office.
