The chairman of global banking giant Credit Suisse, Antonio Horta-Osorio, has resigned with immediate effect after an internal company probe.
He was reportedly found to have broken the UK’s Covid-19 quarantine rules.
The former boss of Lloyds Banking Group joined Credit Suisse after a series of scandals at the Swiss bank.
Now, Mr Horta-Osorio, who was the chairman of Credit Suisse for just eight months, has been replaced by board member Axel Lehmann.
“I regret that a number of my personal actions have led to difficulties for the bank and compromised my ability to represent the bank internally and externally,” Horta-Osorio said in a statement issued by the bank.
“I therefore believe that my resignation is in the interest of the bank and its stakeholders at this crucial time,” he added.
Last month, it was reported by the Reuters news agency that a preliminary investigation by Credit Suisse had found that Mr Horta-Osorio had breached Covid-19 rules.
He reportedly attended the Wimbledon tennis finals in July at a time when the UK’s Covid-19 rules required him to be in quarantine.
Speaking to the BBC, a spokesperson for Credit Suisse said that the bank would give no further details on Mr Horta-Osorio’s resignation other than those in its statement.
They also said that there were no plans to release the findings of the investigation.
Before joining Credit Suisse Mr Horta-Osorio was chief executive of British lender Lloyds Banking Group.
He was brought in to lead Switzerland’s second-largest bank to help clean up a corporate culture marred by its involvement with collapsed investment company Archegos and insolvent supply chain finance firm Greensill Capital.
In February 2020, then-Credit Suisse chief executive Tidjane Thiam resigned after a scandal revealed the bank had spied on senior employees.
