London attacker let into UK despite saying he was ‘going to be a terrorist’ as questions grow over lapses

Youseff Zaghba was placed on an international ‘watchlist’ of suspected foreign fighters after the Italian police caught him trying to travel to Syria last year.

The Italians claim both MI6 and MI5 were informed of the fears surrounding Zaghba, who told police he was “going to be a terrorist” when he was stopped at Bologna airport.
