Iran's million-barrel conundrum brings battle back inside Opec

Dubai

JUST when it looked like Opec (Organization of the Petroleum Exporting Countries) was winning the war with US shale-oil drillers, a new front is opening up within its own ranks.

The Opec's summit on June 5 to determine the group's output will come three weeks before a deadline for a deal on Iran's nuclear programme. The government in Teheran says it can add almost one million barrels to daily production within six months of sanctions being lifted.
