Karl Turner has strongly denied allegations of sexual harassment towards a female party member.
According to the Financial Times a witness claims Karl Turner slapped a woman's buttocks as she walked through his constituency office in Summer 2015.
It's also alleged he told the woman who had a double mastectomy that she "shouldn't have got rid of her real breasts because they were great".
Karl Turner who's represented East Hull since 2010 says he strongly rejects any suggestion of inappropriate behavior.
The Labour Party say anyone with a complaint should come forward so that allegations can be fully investigated.
