Sanctions next if Iran doesn't respond - PM

PORT OF SPAIN (Reuters) - The next stage will have to be more sanctions against Iran if Tehran does not respond to a vote by U.N. nuclear watchdog governors, Prime Minister Gordon Brown said on Friday.

The governors voted overwhelmingly to censure Iran for building a uranium enrichment plant in secret. Brown said such a conclusive vote sent "the clearest possible signal to Iran that they should desist from their nuclear plans, that the world knows what they are doing."

"They should accept the offers that have been made that they can have civil nuclear power with our support, but they've got to renounce nuclear weapons. I believe the next stage will have to be sanctions if Iran does not respond to what is a very clear vote from the world community," he told broadcasters in Trinidad and Tobago where he is attending a Commonwealth summit.
