LONDON -- Various British MPs returned to Parliament on Monday afternoon to pay tribute to the late Labour MP Jo Cox, who was killed last Thursday.

MPs have been seen wearing white roses pinned to their jackets, while Cox's seat in Parliament has been laid with roses.

House of Commons Speaker John Bercow opened the tributes to the 41-year-old Cox, saying her death was "particularly shocking and repugnant."

"Her death strikes at our freedom ...that's why we are assembled here, to honor Jo and redouble our dedication to democracy," he said.

Labour Party leader Jeremy Corbyn agreed the killing was "an attack on democracy." He reminded MPs gathered that Cox would have been 42 on Wednesday, and expressed his best wishes to Bernard Kenny, a 77-year-old man who was stabbed and injured in the attack when he tried to help Cox.
