Bob Malone, the new head of BP's US operations, is establishing his own blog as part of a broader effort by the troubled UK oil company to improve internal communications and keep complaints inside the company.

Mr Malone's blog, to be called Dialogue, follows the recent establishment of a 24-hour complaints hotline, the appointing of an ombudsman to investigate grievances and the mounting of posters at offices in the US urging employees of the company to use both.
