A leader of the campaign for Britain to leave the European Union says the government should ban French far-right leader Marine Le Pen from coming to the U.K. to support the cause.

Le Pen's National Front party says she plans to travel to Britain before the June 23 referendum on EU membership. She backs a British exit, and wants France to hold a similar referendum.

Labour Party lawmaker Gisela Stuart, co-chair of the Vote Leave group, says Le Pen should be banned because of her "divisive and inflammatory comments" about Muslims and others.

U.K. Independence Party leader Nigel Farage says he doesn't support a ban, but considers Le Pen's presence unhelpful and would "rather she didn't come."

Home Secretary Theresa May said Sunday she can't comment on individual immigration decisions.
