Yvette Cooper MP, Labour's Shadow Home Secretary, responding to the resignation of Brodie Clark, said:

"This fiasco gets worse for the Home Secretary. Now her version of events has been contradicted by her most senior official at the UK Border Force. First she decided to reduce border checks then lost control of her so called 'pilot.'

"Now she has lost the loyalty of one of her most senior civil servants. The Home Secretary clearly doesn't know what has been happening at our borders.

"She needs to come to Parliament tomorrow and answer these points urgently. And this shows it is even more important she publishes all the guidance and instructions she gave the border agency so we can tell what has really been going on."
