The Chief Inspector of Borders and Immigration has told ITV Daybreak that a loophole in immigration checks on people entering Britain is "still an issue" and recommends detention facilities at London's St Pancras station to cope with people arriving in this way.
John Vine's comments follow accusations of a "cover-up" by Home Secretary Theresa May after she used legal powers to keep parts of a critical inspection by Mr Vine into UK border controls secret.
In unredacted parts of the report, Mr Vine reveals that border staff remain concerned over the effect of the so-called Lille loophole, which effectively exempts some passengers who travel to Britain via Lille, in France, on Eurostar trains boarded in Belgium, from UK Border Force immigration checks.
