Donald Trump has said he now considers himself the Republican Party's presumptive nominee for the American presidency. He won in all five northeastern states holding primary elections on Tuesday. Nick Bryant is at the Trump campaign headquarters in New York.

Mr Donald J. Trump. With five big wins in five northeastern states, Donald Trump described himself as the presumptive nominee, a boxer as he put it, who just knocked out his opponent and didn't need to await the decision for the referee. But he still needs to win slightly more than half of the remaining delegates to secure the Republican nomination. And his rivals are working together to block his path in upcoming contest such as Indiana next week, a do-or-die moment perhaps for the 'Stop Trump' forces. The billionaire seemed to be looking towards the presidential election, attacking the likely Democratic nominee, who he has taken to calling 'Crooked Hillary'. 'Well I think the only card she has is the women's card. She has got nothing else going. And frankly, if Hillary Clinton were a man, I don't think she will get 5 percent of the vote.' The former Secretary of State beat Bernie Sanders in 4 out of 5 contests, so opening up an insurmountable lead. And she calls the Democrats to come together around her candidacy.

The Venezuelan government has imposed a two-day working week for 2 million public sector workers, an temporary measure to help the country overcome a serious energy crisis. Leonardo Rocha reports.

Venezuela is facing a major draught which has dramatically reduced water levels at the country's main hydroelectric dam Guri. The government has already adopted a number of measures to try to deal with the crisis, including putting the clock forward by half an hour to reduce demands for electricity in the early evening. President Nicolas Maduro says Venezuela has been badly hit by the El Nino weather phenomenon but the opposition accused his government of mismanaging the situation.

The US technology giant Apple has seen its first fall in quarterly revenue since 2003. Apple sales dipped by more than a quarter in China, its most important market after the United States. More from our technology correspondent Rory Cellan-Jones.

Over the last 13 years, a series of ground-breaking products have pushed Apple's sales ever higher and it's grown into the world's most valuable company but now that romp has come to an end. Sales in the last three months were down 12 percent on the same period last year with profits also lower. The main reason was that sales at the iPhone appeared to have pit. It was always going to be hard to beat results which benefit it from a big surge in Chinese sales in 2015. But investors are getting increasingly anxious about the lack of a new blockbuster product to follow the iPhone.

The United States director of National Intelligence has said he's right about what he called a fundamental conflict between the free movement of people across the European Union and the need for national security.

Papua New Guinea says it will close a controversial Australian detention center for asylum-seekers located on Manus Island. The decision follows a ruling by Papua New Guinea's Supreme Court. It said the facility breached the country's constitution.

The Election Commission of the government in exile of Tibet which is based in India has announced that his current leader Lobsang Sangay has been reelected for a second 5-year term of office. The pose was created in 2011 when the Dalai Lama stepped down from his former political roles. Jill McGivering reports.

Lobsang Sangay is a Harvard-educated lawyer who was born in India to refugees. He said he'd never expected to win office the first time round but his reappointment was predicated. He is a moderate voice favoring the so-called middle way, using dialogue and non-violence to purse a goal of autonomy within China, similar to that of Hong Kong and Macao. That won't be easy. China refuses to engage with the government in exile and there is growing concern about the pressure on Tibetan monasteries and the erosion of Tibetan culture.

North Korea has announced that his ruling Workers' Party will hold its first congress in nearly 40 years next month. The gathering will be closely watched for signs of major policy shifts or comment on North Korean's nuclear program.
