Campaigners are expected to protest against the conviction of an asylum seeker for the manslaughter of his fellow migrants who drowned trying to cross the English Channel.Ibrahima Bah, who is over 18, was found guilty of killing four migrants while seeking passage from France to the UK in an “unseaworthy” dinghy he piloted on December 14 2022.During a retrial at Canterbury Crown Court, Bah said smugglers threatened to kill him if he did not pilot the boat, but the prosecution said he was not telling the truth and he owed his fellow passengers a “duty of care” as their pilot.Jurors reached a majority verdict of 10 to two in what is believed to be the first conviction of its kind.
