His widow Barbara sat at the front and was joined by family and friends at the service of ”reflection and solidarity” at Eccles Parish Church in Salford, Greater Manchester.
People of all religions were invited to the service where music was played and candles were lit.
The Church of England Diocese of Manchester said: ”You are welcome to attend this service, whatever faith you have, or if you have no faith.
”It will be an opportunity for reflection and to show support for the Henning family at this tragic time.”
