In Pics: Johnson Leads Tributes to Slain MP David Amess

British Prime Minister Boris Johnson led tributes on Monday in honoring the Conservative lawmaker David Amess.

While leading a somber British Parliament, Johnson told lawmakers that “this House has lost a steadfast servant.”

“Sir David was taken from us in a contemptible act of violence, striking at the core of what it is to be a Member of this House and violating the sanctity both of the church in which he was killed and the constituency surgery that is so essential to our representative democracy,” Johnson said, referring to the open meetings British lawmakers hold with those they represent.

On Sunday, police held Ali Harbi Ali, a British man of Somali origin, under the Terrorism Act on suspicion of murder.

Ali was referred to the counter-terrorist Prevent scheme some years ago, but was never a formal subject of interest to MI5, according to the BBC. Officers have until Friday to question him.

Amess is a veteran lawmaker stabbed to death while meeting constituency voters in an attack that has heightened concern about politicians' safety.

The Prime Minister affirmed that Amess had an outstanding record of passing laws to help the most vulnerable, whether the people who are suffering from endometriosis.
