The funeral of Conservative MP Sir David Amess, who was murdered two weeks ago, will be held at Westminster Cathedral on Tuesday 23 November.
Cardinal Vincent Nichols, will be the main celebrant.
David Amess was fatally stabbed while conducting his regular surgery at a church in Leigh-on-Sea on 15 October.
Cardinal Nichols said at the time: “This death throws a sharp light onto the fact that our Members of Parliament are servants of the people, available to people in their need, especially in their constituencies."
Sir David, 69, was married with five children.
During his 38-year parliamentary career he campaigned against fuel poverty and for animal rights. In 2006, he established the All-party Parliamentary Group for relations with Holy See Group.
