The former boss of Lloyds Bank has admitted breaking Covid rules after returning to Switzerland from the UK last week.
Antonio Horta-Osorio, who is now chairman at Credit Suisse, travelled to Switzerland on Nov 28 where he was required to quarantine for 10 days.
However, he flew to the Iberian peninsula on a private jet just three days later, on Dec 1.
Mr Horta-Osorio had been told by the Swiss authorities that there would be no special exemptions and that he should remain in isolation for the full period.
The banking veteran said: “I unintentionally violated Swiss quarantine rules by leaving the country prematurely on Dec 1. I sincerely regret this mistake. I apologise and will ensure that this does not happen again.”
Credit Suisse said it “regretfully acknowledged” the breach, adding that complying with guidance is a top priority.
Mr Horta-Osorio moved to the UK from Portugal in 2006 to run Santander’s UK arm, then was appointed as chief executive of Lloyds in early 2011.
He returned the bailed-out lender to private ownership and profitability, yet received criticism for conducting an extramarital affair while on a business trip.
The FTSE bank had emerged from the 2008 financial crisis thanks to a rescue deal with the Government.
Taxpayers had bought a 43pc stake in exchange for over £20bn but the state managed to sell all its shares back to the market by 2017.
Former Bank of England governor Lord Mervyn King said that Mr Horta-Osorio turned Lloyds “from a liability to the taxpayer into an asset for the country”.
