Liz Truss and Sir Keir Starmer have led tributes to Sir David Amess on the first anniversary of his death.
Sir David, had been an MP for nearly 40 years, when was stabbed to death by an extremist during his constituency surgery in Leigh-on-Sea, Essex, on October 15 last year.
He is survived by his wife Lady Julia Amess and their three children.
The Prime Minister tweeted a statement along with Sir David’s parliamentary portrait on Saturday morning.
She wrote: “On the anniversary of Sir David Amess’ death, we cherish his memory and remember his enormous contribution to politics, to the people of Southend and to the country.
“My thoughts today are with his wife Julia, the Amess family and to all those who knew and loved him.”
Labour leader Sir Keir wrote on Twitter: “Remembering our friend & colleague David Amess, on the 1st anniversary of his senseless death.
“David’s commitment to public service, carried out with inherent, consistent kindness, will forever be admired.
“Thinking of his wife & children, hoping memories of him bring comfort.”
Southend-on-Sea council be planted in Sir David’s memory at Chalkwell Park on Saturday morning.
The tree was planted using compost from flowers left across the area in the days and weeks following the MP’s death, the council said.
Stephen George, leader of the council, said: “A kind family man, Sir David was devoted to his local constituency of Southend West and was the greatest champion of Southend-on-Sea and local area.
“He is greatly missed and we hope that we can remember him in an appropriate way by planting a memorial tree at one of his favourite local parks.”
Southend mayor Kevin Robinson said: “Whilst we reflect on the awful and tragic events of October 15, 2021, we must also be thankful for the life that Sir David lived and the many lives that he touched and changed both locally and beyond.
“Southend-on-Sea would not be a city with the continued commitment of Sir David to make it happen, and as the first freeman of the city of Southend-on-Sea, he will always be the most important part of our history as a city.”
The 69-year-old, who had campaigned to make Southend-on-Sea a city and was posthumously made the first freeman of the new city, had served Southend West since 1997, and before that, Basildon since 1983.
Ali Harbi Ali, 26, who attacked the veteran MP in a warped retaliation against politicians who voted to bomb Syria, was handed a whole-life prison term in April this year after a trial at the Old Bailey.
