Britain willing to work on alternative Iran nuclear deal - PM's spokesman

LONDON (Reuters) - Britain is willing to work towards an alternative deal to prevent Iran obtaining nuclear weapons if it has U.S. support, but for now the current deal is the only one in place, Prime Minister Boris Johnson's spokesman said on Tuesday.

Earlier, France, Britain and Germany confirmed they had triggered the dispute mechanism in the Iran nuclear deal given Tehran's ongoing violations, but said they were not joining the United States' campaign to exert maximum pressure on Tehran.
