A Tory colleague, MP Tim Loughton described Hancock as an “absolute prat”.
Hancock has also faced calls from opposition critics to give up his £84,144 a year MP’s salary while he is in the jungle.
In a statement, his local West Suffolk Conservative Association said it was “disappointed” and accused Mr Hancock of a “serious error of judgement”.
