A member of the Nigerian Olympic boxing squad who came to the UK for the London 2012 Games was locked up in immigration detention despite marrying a British woman who is pregnant with his child.

Adedayo Victor Daodu, 25, known as Victor, arrived in the UK in June 2012 to train as a sparring partner with the Nigerian team.

Last week he was sent to Dungavel immigration removal centre in South Lanarkshire and threatened with imminent deportation back to Lagos, to the horror of his Wigan-born wife, Robyn, who is seven months pregnant with their first child. It is the second time he has been detained by immigration officers and sent to Dungavel this year.

Robyn’s parents, both psychiatric nurses, have begun a campaign to keep their family – and unborn grandchild – in the country.

In a letter to the Home Office, they wrote: “When we first met Victor we were both sceptical about his intentions and questioned him relentlessly about who he was and what he was all about.
