An estimated 58 percent of respondents said Cameron was performing "badly" in his job, compared with 52 percent who expressed the same opinion of Corbyn, according to a YouGov poll.
A mere 34 percent said the prime minister was "doing well," marking the first time his approval rating dropped that low since July 2013.
The survey was conducted among 1,612 adults on April 6-7, before Cameron admitted to profiting from his late father’s offshore company linked to the Panamanian law firm Mossack Fonseca.
On April 3, Germany’s Sueddeutsche Zeitung daily published materials it alleged came from Mossack Fonseca. The 11.5 million leaked files were claimed to expose the alleged involvement of former and current world leaders, among others, in establishing offshore companies through the law firm.
Cameron's first reaction on Tuesday was to deny owning any shares, dismissing it as a private matter. He admitted on Thursday, however, he had sold his share worth 30,000 pounds ($42,000 at the current exchange rates) in the Blairmore Holdings 5 months before assuming office.
Cameron insisted that his father’s fund was not set up to avoid taxes and stressed that he had nothing to hide about his financial affairs.
Mossack Fonseca has refused to validate the information contained in the leaks and accused reporters of gaining unauthorized access to its proprietary documents. The Panamian company warned that using unlawfully-obtained data was a crime that it would not hesitate to punish by legal means.
