Twitter co-founder Jack Dorsey is stepping down as chief executive of the company.
He will be replaced by the current chief technical officer, Parag Agrawal, Twitter said in a statement.
Mr Dorsey, who co-founded Twitter in 2006, has been serving as chief executive of both Twitter and payment firm Square.
“It’s finally time for me to leave” he wrote in a statement, saying the company was “ready to move on.”
Mr Dorsey said he had “deep” trust in his replacement. “I’m deeply grateful for his skill, heart, and soul. It’s his time to lead,” he said.
Mr Agrawal joined Twitter in 2011, and has been the firm’s head of technology since 2017.
At the start of this year Twitter took the extraordinary step of permanently banning a sitting US president from the service following the insurrection at the US Capitol.
But under Dorsey’s leadership, Twitter has struggled to design and enforce an ever more complex set of policies and rules for its users, including world leaders.
