Sir David Amess's French Bulldog Vivienne named Westminster Dog of the Year

Watch: ITV News Correspondent Phil Hornby reports from Westminster.

The late Sir David Amess's French Bulldog Vivienne has been named Westminster Dog of the Year.

The Prime Minister congratulated the animal, which had been entered into the annual competition by Southend West MP Sir David before he was stabbed to death in his constituency earlier this month.

Earlier this week Boris Johnson had urged members of the public to vote for Vivienne, saying it would be a wonderful tribute to the late MP.

Sir David had previously entered his pets into the competition multiple times, which celebrates the bond between them and their Parliamentarian owners.

As part of the entry, Sir David had said Vivienne "lifts my spirits as she is always pleased to see me and she makes me smile".

He added: "Every time I walk into the room Vivienne throws herself at me, lies on their back with her legs in the air to be tickled.

"But before that she always brings a toy so she is of a generous, giving nature."

The Southend West MP described himself as a "great animal lover" on his website, something that was reflected in his record in Parliament.

Conservative MPs Andrew Rosindell and Mark Francois collected the award with three-year-old Vivienne, who was seen wearing a City of Southend neckerchief.

Boris Johnson tweeted: "Congratulations Vivienne. David would have been very proud."
