Cameron hoping to send tough message over Ukraine

Greenhouse gas emissions should be cut to the "upper end" of the recommended 40 to 70 per cent range by 2050, the G7 has declared.

Environmental campaigners welcomed the summit's support for "deep cuts" to emissions, with an intention to completely wipe out the world economy's dependence on carbon by the end of the century.

Greenpeace UK's executive director, John Sauven, said it signalled that "the age of fossil fuels is coming to an end".

Oxfam's G7 spokesman, Jorn Kalinski, also welcomed the promise, but urged leaders to keep their promise to invest $100 billion (£65bn) for climate change action in developing countries.

US President Barack Obama has called for more cooperation between nations to try to stem the flow of foreign would-be jihadists into Syria.

Speaking at the close of the G7 summit in Germany, he said while coalition forces had managed to successfully target many Islamic State strongholds, the continuing influx of fighters from overseas meant a long-term solution was still some way off.

He said he wanted to see "better cooperation, better coordination and better intelligence" - including an improvement in the monitoring of the border between Turkey and Syria.

He said the US was also stepping up efforts to train Iraqi soldiers to fight Islamic State extremists, as well as working with Iraq's government to improve cohesion between the Sunni, Shia and Kurdish communities.

David Cameron is hoping to send a tough message on Ukraine from the leaders of the West's largest powers as the G7 summit in Germany concludes.

The Prime Minister held talks with US president Barack Obama at which both agreed the need to maintain harsh sanctions against Russia until Moscow shows it has fully implemented last year's Minsk peace agreement.

The summit's host, German chancellor Angela Merkel, said she is hoping for a strong G7 statement in support of continued sanctions against Russia.

EU leaders must decide at a summit in Brussels at the end of June whether to renew economic and financial measures which would otherwise lapse in July.

Russia was ejected from the G8 last year following its annexation of Crimea and interference in eastern Ukraine, where Western nations allege it has given military backing to separatist rebels - something President Vladimir Putin denies.

US President Barack Obama has said that America is "looking forward" to the United Kingdom remaining part of the European Union.

Mr Obama's comments came as he met Prime Minister David Cameron for talks in the margins of the G7 summit of world leaders in Schloss Elmau, Germany.

They are the strongest indication yet that Washington wants a Yes vote in the referendum which Mr Cameron has promised by the end of 2017 on whether Britain should stay in the EU.

Greeting Mr Cameron at the start of the bilateral talks, Mr Obama said the US-UK relationship remains strong, telling reporters: "We have no closer partner around the world on a whole host of issues."

And he added: "I would note that one of the great values of having the United Kingdom in the European Union is its leadership and strength on a whole host of global challenges, so we very much are looking forward to the United Kingdom staying part of the European Union because we think its influence is positive not just for Europe, but also for the world."

Anti-G7 summit protesters have staged protests as world leaders gather for the first day of the talks.

Prime Minister David Cameron joined Canadian Prime Minister Stephen Harper, US President Barack Obama and French President Francois Hollande as they posed with host German Chancellor Angela Merkel.

David Cameron is expected to call on leaders at the G7 summit to help eradicate global corruption in the wake of the Fifa scandal.

Speaking ahead of the gathering, he said, "Corruption is the cancer at the heart of so many challenges in our world".

"I'm putting it on the table here, and saying this is something we must not turn a blind eye to as perhaps was done for too long with the world of football."

Prime Minister David Cameron has arrived in Germany for the G7 summit.

He was greeted by locals in traditional Bavarian costume and dignitaries as he stepped off a plane at Munich airport.

US President Barack Obama enjoyed a beer ahead of the G7 summit in Germany today.

Earlier, he joked that he had hoped the summit would fall during Oktoberfest - an annual beer festival - but "there's never a bad day for a beer".
