Nick's story is a particularly striking example of how a British citizen became involved in the international people-smuggling trade. His "stories and confessions represent a concerning risk posed to the UK around people smuggling and irregular migration at sea", said Border Force's Charlie Eastaugh. We will "look at the vulnerabilities he [Nick] has identified," he added. Unlike many migrants crossing the English Channel in small boats, the majority of those transported by Nick did not want to be found by authorities to formally claim asylum. Having arrived on UK shores, they wanted to disappear anonymously into the black economy. Nick said he had been told the Vietnamese migrants would go on to work on cannabis farms. The fact that Nick travelled with them too - skippering a yacht - is also unusual. It all started in 2009, when an Albanian friend he met on a construction site recruited him - saying Nick's pale complexion and UK passport would help him to avoid suspicion from border authorities. The friend, whom we are calling Matt, offered to pay Nick £3,500 for every migrant he smuggled into the UK. Nick was working as a self-employed builder at the time, but his business had been pulled under by the financial crash in the late 2000s and he was struggling to make ends meet. He also had a baby on the way and was desperate to provide for them, he told us. Matt spoke briefly to the BBC and confirmed details of Nick's story - but we did not move forward with a full interview because he demanded payment.
