Opec is missing a return ticket for its trip back to 2014

London

THE benefits of Opec's agreement to cut output have proved elusive. With less than three weeks to go before the group's next meeting, something is very, very wrong as far as oil producers are concerned. And they have no easy solution to put it right.

The oil price is not far off where it was in November, before Opec and friends agreed to cut output - Brent briefly fell to within 30 US cents a barrel of its pre-meeting price during early trading on Friday.
