Events will test Cameron and Obama alliance
IN a spirit of unyielding optimism, neatly combined with a message of hard-headed pragmatism, Barack Obama has insisted that the time for American and European leadership "is now", in spite of the rise of new global superpowers.
He was the first US president to address British MPs and peers in Westminster Hall and received a standing ovation before he even began his speech, which covered issues such as foreign policy, economic development and security.
The theatre of a state visit from Mr Obama is unavoidably mesmerising. But the spell could not entirely obscure the limits of the message in his partly platitudinous speech and the awkward, plodding press conference that preceded it.
