The Colombian government and Farc rebels say they have reached a definitive bilateral ceasefire in Latin America's longest running armed conflict. The main issue - the disarmament of the rebels - has been addressed. And, after half a century of war, the Colombian President Juan Manuel Santos has said a final peace deal could be signed by late July. There have been plenty of reports of peace before, so is this really it? We hear from the BBC's Natalio Cosoy in Bogota.

California's last nuclear power plant will close by 2025 under a proposal announced on Tuesday, with safety concerns given as the main reason. But the Diablo Canyon plant produces enough power for 1.7 million homes. There is now a plan to replace the energy with renewables, though some environmentalists do not think they will be able to match that produced by nuclear. However, Erich Pica, president of Friends of the Earth US, says he is celebrating the closure of the plant.

Are we heading towards a cashless society? It is a subject of intense debate in financial circles. The Danish and Swedish government have said they expect their countries to go entirely cashless in the future. In the UK, contactless card transactions have risen by a third over the past year and a Mastercard survey shows one in four Britons intend to make payments with their phone over the next 12 months. Most retailers have adapted to the trend but what about individual traders and organisations who have relied on cash donations to survive? The BBC's Susannah Streeter reports.

We are joined by two guests on opposite sides of the Pacific - Peter Morici, professor of International Business at the University of Maryland - who is in Washington, and Simon Long Asia editor of The Economist in Singapore.
