An independent investigation into BP's Texan refinery disaster has concluded that there were serious structural deficiencies in the way the company managed safety stretching right up to its London headquarters.
The conclusions will be published on Tuesday in a damning report from a panel led by James Baker, the former US secretary of state, that casts new light on the pressures building up against Lord Browne, the chief executive, before his surprise retirement announcement on Friday.
According to sources who have seen copies of the 250-page report, it focuses on failings in "process safety management" that undermine previous claims that BP's problems in North America have all been isolated incidents.
"The report finds the problems go all the way to the top and to talk about what happened in Texas City you have to talk about what happened in London," said one. "There is no level of the company that is exempt from responsibility."
