G8 nations have agreed a joint position on Syria at a summit in Northern Ireland, which could pave the way for fresh peace talks in Geneva.
The G8 has just published its statement on tax avoidance and transparency and it is not yet clear what impact he deal will actually have.
If the body language between Presidents Obama and Putin is anything to go by, this summit has been a disaster.
David Cameron gave world leaders at this year's G8 meeting a compilation album as a gift - but unexpectedly it contained music to turn the airwaves blue.
Leaders, including US president Barack Obama, Russia's Vladimir Putin and chancellor Angela Merkel of Germany were all given the gift of a USB stick featuring 10 songs at the gathering in Northern Ireland last month.
The stick, which included tracks by Mercury Prize winners Alt-J, Jake Bugg and Rudimental, featured Tom Odell's hit Another Love.
The song, a top 10 hit earlier this year, is marked "explicit" on digital music site Spotify and includes the lyrics "So I'll use my voice, I'll be so f****** rude. Words they always win, but I know I'll lose".
David Cameron will face questions from MPs after G8 leaders thrashed out limited agreements on how to handle the Syria crisis and tackle tax dodging.
The Prime Minister is due to make a statement to the Commons after claiming to have achieved significant progress at the summit of wealthy countries at Lough Erne, Northern Ireland.
In a joint statement, the eight nations said a planned conference on ending the conflict in Syria should be held "as soon as possible".
After two days of talks in Northern Ireland, G8 leaders endorsed a plan to restart peace talks in Geneva "as soon as possible".
Despite Russia's support of President Assad's regime - it along with the UK, US, France, Germany, Italy, Canada and Japan - made a commitment "to achieving a political solution to the crisis based on a vision for a united, inclusive and democratic Syria".
ITV News' Political Editor Tom Bradby reports.
G8 leaders in Fermanagh have signed a Lough Erne Declaration, which seeks to clamp down on tax evasion by companies at a global level.
The co-ordinated action is the first deal of its kind, but it is unclear how effective it will be. Business Editor Laura Kuenssberg reports.
Prime Minister David Cameron has hailed the "important breakthroughs" made at a summit of G8 leaders in respect to a shared consensus on tacking the Syria crisis.
But he also conceded that there remains "frustration" in respect to the ongoing situation.
He told ITV News: "Every day without a peace conference, every day of bloodshed and slaughter is a day of immense frustration.
But he added: "Let's be clear what we've agreed here - which is a proper road map to a transition and also to having an end to Assad and a government that all of Syria can support - those are all important breakthroughs and we have taken some good steps forward to bringing this conflict to an end".
The Trade Union Organisation (TUC) have labelled the Lough Erne tax declaration "so weak it is bordering on irrelevance," and "yet another missed opportunity." Frances O'Grady, general secretary of the TUC said:
For all the prime minister’s welcome pre-summit rhetoric, the G8 declaration fails to deliver what’s needed to tackle tax avoidance, and even falls short of the expectations he’s set.
While some progress has been made on automatic information exchange, the agreement on reporting profits to tax authorities is so weak it is bordering on irrelevance.
Despite the high profile pre-summit lobbying, the British crown dependencies appear to have outmanoeuvred the G8 nations and got tax havens out of the agreement altogether.
We fear the declaration’s warm platitudes and hazy rhetoric will be far too easy for global companies to skirt around. Yet another opportunity has been missed to finally get to grips with global tax avoidance and evasion.
US President Barack Obama has said that it is important to build a strong opposition in Syria that can function in a post-Assad situation.
Speaking after G8 leaders agreed new measures to tackle the crisis in Syria, Mr Obama said: "We very much share the view that it is important for us to build on the G8 communique to move towards a political transition".
"We will continue to work to try and find a poltical solution to this process and most importantly alleviate suffering and ensure that chemical weapons are not used by anyone inside of Syria".
Russia's President Vladimir Putin has insisted that Russia's arms supplies to Syria are legal and do not violate moral principles, Reuters reports.
He also said he will not rule out new arms contracts with Syria's government.
Mr Putin added that any arms supplied to Syrian rebels could one day end up being used in Europe.
