David Cameron is to discuss the oil spill crisis with President Barack Obama, after shares in BP plunged to their lowest level in more than 13 years this morning.
A spokesman for the prime minister said he was “sure” that the pair would speak about BP during a telephone call this weekend, in a further sign that the Deepwater Horizon disaster has now escalated into a political issue.
“The prime minister understands that there are many people who are angry and emotional about what has happened,” said Cameron’s official spokesman.
“This is an environmental tragedy and the impact will be much broader than the environmental impact, and that is why we are encouraging BP to find a solution as soon as possible,” he added.
