BBC: Gordon Brown and President George Bush have warned Iran to accept their "offers of partnership" or face tough sanctions and international isolation.
The UK prime minister said he wanted to maintain a dialogue with Tehran, but if Iran ignores UN resolutions then sanctions would be intensified.
Europe would freeze overseas assets of Iran's biggest bank and impose new oil and gas sanctions, he said.
But the EU foreign policy chief said no new sanctions had so far been agreed.
