US split would damage morale
Prime Minister Tony Blair has told Cabinet colleagues that any open disagreement with the US over Iraq risked damaging troops' morale.
The point was also underlined by Foreign Secretary Jack Straw and Defence Secretary Geoff Hoon, said Mr Blair's official spokesman.
He said their comments came during a brief Cabinet discussion about progress towards the handover of sovereignty in Iraq on June 30.
Mr Blair's remarks came after Tory leader Michael Howard urged him to be more open about any disagreements with America.
