And Straw complied. From [1] The Guardian, with thanks to JE:

Kofi Annan told Jack Straw of his anger at Britain's stance on the conflict in a phone call last Wednesday to the former foreign secretary, it emerged last night. The UN secretary general rang Mr Straw hours after Britain and the US blocked a call for an immediate ceasefire at the Rome summit, and a day after Israel bombed a UN monitoring position, killing four observers.

Two days later Mr Straw broke rank publicly, attacking Israel's "disproportionate" actions.
