Did you really believe Theresa May's promises?

Guido Fawkes https://order-order.com/2018/08/24/customs-union-u-turn/ has found something interesting:

'The Department for International Trade is interviewing for a 'Business Support Manager'. The second bullet point in the five "key areas of responsibility" gives away that the department is developing policy about membership of the Customs Union. 

This directly breaks one of Theresa May's most important red lines…

"Customs Union: with G7 support, leading BEAT's [Business Environment Advisory Team] engagement with those developing the policy about the UK's membership of the Customs Union, as it develops."

Trade Secretary Liam Fox has consistently said that "no form of customs union is acceptable after Brexit" and that membership of one would constitute "a complete sell-out of Britain's national interests." His department seems to disagree…'
