LONDON - One is Liz Truss, Britain's former foreign secretary and now prime minister. The other is Liz Trussell, an ordinary Twitter user.

But having snapped up the @Liztruss Twitter handle more than a decade ago, the "other Liz Truss" has suddenly found herself bombarded with messages intended for No. 10 Downing Street's newest resident, whose handle is @trussliz.

Sweden's Prime Minister Magdalena Andersson was among those who managed to mistakenly congratulate Ms Trussell, who has been revelling in the confusion, firing back with wisecracks and jokes.

"Congratulations to Liz Truss," Ms Andersson wrote, adding that "Sweden and Great Britain will continue our deep and extensive cooperation".

"Looking forward to a visit soon!" Ms Trussell replied. "Get the meatballs ready."

Among others who got the two mixed up - after Ms Truss won the contest to be the new Conservative Party leader and replace Mr Boris Johnson as premier - were MP and Green Party leader Caroline Lucas.

Ms Lucas berated Ms Truss in her tweet for being a "right-wing ideologue" and predicting her tenure at No. 10 would be a "disaster for all of us". She later apologised, adding that Ms Trussell would "probably make a better job" of leading the country.

"I'm in! Vegas for everybody," responded Ms Trussell, who has around 3,400 followers compared with Ms Truss' over 360,000.

Ms Trussell, whose Twitter photo shows her in high spirits dressed in a pink party dress, has certainly been enjoying her moment in the limelight.

After Ms Truss was accused on Twitter of snubbing her rival for the Tory leadership Rishi Sunak by not shaking his hand before her victory speech, Ms Trussell explained she had been busy at a restaurant.

"Sorry, I was in Nandos," she responded.

And her humorous responses have won her plenty of admirers, with one local politician proposing a petition in her support.

"Petition for @Liztruss to become PM tomorrow in place of @trussliz," wrote Mr Matt Dent.

Another, Mr Jake Graham, suggested the Tory party just ditch the real Liz Truss and go with Ms Trussell.

"Liz Trussell who has the @Liztruss Twitter handle looks like an absolute hun! Can we please have her as PM instead?"
