Pc Keith Palmer was a "wonderful dad and husband, a loving son, brother and uncle" who will be "deeply missed", his family said.

The 48-year-old married father, who was killed in the Westminster terror attack, was "dedicated to his job and proud to be a police officer, brave and courageous".

In a statement, his family added that he was a "long-time supporter of Charlton FC", and a "friend to everyone who knew him".

They said: "He will be deeply missed. We love him so much.

"His friends and family are shocked and devastated by his loss and ask that they are left to grieve alone in peace."

Pc Palmer was stabbed to death in the attack on Wednesday while on duty at the Houses of Parliament.

He joined the Parliamentary and Diplomatic Protection Command in April 2016, having previously worked in the Territorial Support Group (TSG).

Pc James Aitkenhead, who worked alongside Keith in the TSG, praised his former colleague as a "genuinely nice person" for whom "nobody had a bad word to say".

"When I heard what had happened I knew it would be him because that's just the sort of guy he was, to step straight in when others might step back."

He said Pc Palmer had a "great work ethic" and "was always so positive, always staying late after everyone else and getting in early".

Pc Aitkenhead added: "We will miss him so much."

Inspector Mark Turner, from the Parliamentary and Diplomatic Protection Command, who most recently worked with Pc Palmer, said: "He really was a solid reliable member of the team - he came in and just got the job done, quietly and efficiently.

"He was a fantastic member of staff and will be sorely missed."
