Suspended Labour MP Kelvin Hopkins said he wants to “clear his name” after denying claims of sexual harassment.
Labour activist Ava Etemadzadeh, 27, told the BBC that Mr Hopkins had hugged her inappropriately after a student event in 2014.
The Luton North MP said he had only “put an arm around her” and did not hold her tight.
The Labour Party said it “takes all complaints of sexual harassment extremely seriously”.
Mr Hopkins was suspended by the Labour Party last year and now represents his constituency as an Independent.
He said: “I have been waiting eight months for a hearing to clear my name and I have heard nothing so far.
