Ibrahim Dogus is to replace Tom Watson as a Labor Party candidate for West Bromwich East after the deputy leader has declared that he will not run again.
Mr. Dogus, a restoration contractor and union advisor, is the current mayor of Lambeth.
Mr Watson, an MP for 18 years, announced the first day of his election campaign that he would step down.
He cited "personal, not political" reasons for his decision.
Mr Dogus, who owns three restaurants in London, said he was "proud" to have been selected as a candidate and "would not waste time fighting the conservatives".
"I would like to pay tribute to Tom Watson, who has diligently served the residents of West Bromwich East," he added.
"I'm proud to call him a friend and acknowledge that I have a lot of difficulties completing as a Labor Party candidate."
He stated that he was eager to "meet locals and listen to their concerns".
"I look forward to fighting for local people, standing up for communities and businesses, and providing the decent services people deserve here."
Earlier this year, Mr. Dogus received death threats on social media for putting an anti-Brexit message on receipts from his restaurants.
He refused to delete the following message: "Brexit is bad! Immigrants make Great Britain! They have also cooked and served your food today."
