the opposite to Mr. Brown.

"It wasn’t all bad news: Mr Brown’s address to Congress was a success.

The White House was surprised to learn there were reports in the UK that Mr Obama had snubbed him and went out of its way to praise Mr Brown."

However, the article does mention that:

"Things got worse when Mr Brown landed in Washington and he learned – to his horror – that back in the UK, Chancellor Alistair Darling had defied him by saying the complete opposite. Mr Darling said in an interview: ‘If there is a fault it is our collective responsibility. All of us have to have the humility to accept that over the last few years things got out of alignment.’

‘Fault’ and ‘humility’ are two words Mr Brown refuses to use. Now he was furious. Frantic calls were made to the Treasury from No10 aides in Washington demanding to know why Mr Darling had ‘stepped out of line’."

I would say that incident "sweetened the pot" a bit.
