I’ll never forget the moment I found out that a group of people had blocked a charter deportation flight leaving Stansted airport on 28 March 2017, because I was one of the people that had a seat on the plane and was about to be removed from Britain against my will. While most of those sitting with me were whooping with joy when they heard the news, I was angry. After months in detention, the thought of facing even just one more day in that purgatory filled me with terror. And, crucially, I had no idea then of what I know now: that the actions of those activists, who became known as the Stansted 15, would help me see justice, and save my life in Britain.

I first arrived in Britain in 2004 and, like so many people who come here from abroad, built a life here. As I sat in that plane in Stansted last year I was set to be taken “back” to a country that I had no links to. Indeed there is no doubt in my mind that had I been deported I would have been destitute and homeless in Nigeria – I was terrified.

Imagine it. You’ve lived somewhere for 13 years. Your mum, suffering with mobility issues, lives there. Your partner lives there. Two of your children already live there, and the memory of your first-born, who died at just seven years old, resides there too. Your next child is about to be born there. That was my situation as we waited on the asphalt – imagining my daughter being born in a country where I’d built a life, while I was exiled to Nigeria and destined to meeting my newborn for the first time through a screen on a phone.

My story was harsh, but it’s no anomaly. Like many people facing deportation from the United Kingdom, my experience with the immigration authorities had lasted many years – and for the last seven years of living here I had been in a constant state of mental detention. A cycle of Home Office appeals and its refusal to accept my claims or make a fair decision based on the facts of my case saw me in and out of detention and permanently waiting for my status to be settled. Though the threat of deportation haunted me, it was the utter instability and racial discrimination that made me feel like I was going mad. That’s why the actions of the Stansted 15 first caused me to be angry. I simply didn’t believe that their actions would be anything more than a postponement of further pain.

My view isn’t just shaped by my own experience. My life in Britain has seen me rub along with countless people who find themselves the victims of the government’s “hostile environment” for migrants and families who aren’t white. Migration and deportation targets suck humanity from a system whose currency is the lives of people who happen to be born outside the UK. Such is the determination to look “tough” on the issue that people are rounded up in the night and put on to brutal, secretive and barely legal charter flights. Most take off away from the public eye – 60 human beings shackled and violently restrained on each flight, with barely a thought about the life they are dragged away from, nor the one they face upon arrival.

I was one of the lucky few. My removal from the plane gave me two life-changing gifts. The first was a chance to appeal to the authorities over my deportation – a case that I won on two separate occasions, following a Home Office counter-appeal. But more importantly the brave actions of the Stansted 15 gave me something even more special: the chance to be by my partner’s side as she gave birth to our daughter, and to be there for them as they both needed extensive treatment after a complicated and premature birth. Without the Stansted 15 I wouldn’t have been playing football with my three-year-old in the park this week. It’s that simple. We now have a chance to live together as a family in Britain – and that is thanks to the people who lay down in front of the plane.

On Monday the Stansted 15 were found guilty of breaching a barely used terror law. Though the jury were convinced that their actions breached this legislation, there’s no doubt in my mind that these 15 brave people are heroes, not criminals. For me a crime is doing something that is evil, shameful or just wrong – and it’s clear that it is the actions of the Home Office that tick all of these boxes; the Stansted 15 were trying to stop the real crime being committed. As the Stansted 15 face their own purgatory – awaiting sentences in the following weeks – I will be praying that they are shown leniency. Without their actions I would have missed my daughter’s birth, and faced the utter injustice of being deported from this country without having my (now successful) appeal heard. My message to them today is to fight on. Your cause is just, and history will absolve you of the guilt that the system has marked you with.
