Llywydd at the Senedd Elin Jones has spoken of her "shock and sadness" at news of Sir David Amess' death.

Sir David, who represented Southend West in Essex, was attacked on Friday at Belfairs Methodist Church in Leigh-on-Sea.

Police have confirmed that a 25-year-old man has been arrested on suspicion of murder.

They said they recovered a knife and were not looking for anyone else in connection with the incident.

Sir David, 69, had been an MP since 1983 and was married with five children.

“I’m deeply shocked and saddened by the death of Sir David Amess," said Ms Jones in a statement.

"Our democratic process depends on our elected members being able to listen and talk to the public we serve.

"It should go without saying that every elected member should be able to carry out this work safely and without fear.

"As members we may have different views, but we are always united in our respect for the democratic process and our commitment to serving the public.

"My thoughts are with his family, friends and colleagues.”

Wales' First Minister Mark Drakeford paid tribute on Twitter by saying: "Deeply saddened to hear about the death of Sir David Amess.

"A truly despicable and horrifying act. My thoughts are with his friends, family, and constituency staff during this distressing time."

Conservative Senedd leader Andrew RT Davies wrote on Twitter: "Shocked, appalled and devastated to hear Sir David Amess MP has passed away.

"He served with pride as MP for almost four decades, representing his constituents and our country with loyalty and dedication. My thoughts are with his family at this tragic time. May he rest in peace."

Plaid Cymru leader Adam Price, a former MP, said it was an "honour" to call Sir David a friend.

He wrote on Twitter: "Shocked and deeply saddened to hear this terrible news.

"Sir David was one of the kindest, most decent and deeply committed politicians I’ve ever known. It was an honour to call him a friend.

"My thoughts are with his loved ones during this awful time."

Welsh Liberal Democrat leader Jane Dodds also paid tribute on Twitter.

She wrote: "I am utterly devastated to hear of the death of David Amess.

"This is a shameful act of violence that no public servant should face.

"My thoughts and prayers are with David's family, friends and colleagues at this horrendous time."

Essex Police said they received reports of a stabbing shortly after 12:05 BST and found a man injured. He was treated by emergency services but died at the scene.

Sir David is the second sitting MP to be killed in the last five years, following the murder of Labour MP Jo Cox in 2016.
