Reuters - Britain will push to curb energy and financial investment in Iran unless Tehran addresses nuclear concerns, Prime Minister Gordon Brown said on Monday in a speech that also underlined Washington's importance as an ally.

The New York Times - Britain will push for a worldwide ban on foreign investment in Iran’s oil and gas industry and other financial sanctions unless two reports due this month show that the Tehran government is ready to abandon efforts to acquire nuclear weapons, Prime Minister Gordon Brown said Monday.

The Times - Gordon Brown last night proposed a worldwide ban on companies developing Iran’s oil and gas fields if it failed to curb its nuclear ambitions.

The Guardian - Gordon Brown declared last night that Britain "will lead" the international campaign to stop Iran's nuclear programme, calling for new sanctions on oil and gas investments in the Islamic republic if it fails to comply with UN resolutions.
