Conservative MP Anna Firth welcomed into House of Commons after Southend West by-election victory

The successor to Sir David Amess as Southend West has taken her seat in the House of Commons, following a by-election triggered by the killing of the veteran MP.

Conservative Anna Firth swore the oath of allegiance to the Queen as she appeared in the House of Commons chamber ahead of work and pensions questions.

She was welcomed by Tory colleagues and joined by fellow Essex MPs Mark Francois (Rayleigh and Wickford) and James Duddridge (Rochford and Southend East).

Ms Firth said: “I swear by almighty God that I will be faithful and bear true allegiance to Her Majesty Queen Elizabeth, her heirs and successors, according to law. So help me God.”

She went on to exchange a few words with Commons Speaker Sir Lindsay Hoyle.

A by-election was held in Southend West after former incumbent Sir David was killed at Belfairs Methodist Church in Leigh-on-Sea, Essex on October 15 during a constituency surgery.

The 69-year-old had served Southend West since 1997, and Basildon before that since 1983.

Following her victory, qualified barrister Ms Firth vowed to “work tirelessly to build on everything” achieved by Sir David during his lengthy tenure.
