Border Agency whistlebower: 'Corners had to be cut'
Home Secretary Theresa May has admitted she does not know how many people came into the UK without proper checks.
An inquiry has been ordered into claims identity checks on travellers from outside Europe were scaled back in the summer, without ministerial approval.
In a statement to MPs, Mrs May said those responsible would be punished. Brodie Clark, head of the UK border force, is among three staff suspended.
Labour accused Mrs May of giving "the green light for weaker controls".
