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.
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".
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.
Prime Minister David Cameron outlined the key agreements on tackling the crisis in Syria made between G8 leaders after a two-day summit in Lough Erne, Northern Ireland.
He said: "It is no secret there were very different views around the G8 table but we all share a vital interest in bringing this conflict to an end".
Russia's President Vladimir Putin has said that he did not feel isolated at talks with G8 leaders on the situation in Syria.
"We had disagreements that is true but I never felt lonely and Russia never was on its own in making a statement in regards of Syria.
"Clearly some wanted to have more details and others less but it was a joint discussion with great interest demonstrated, people who want to find a very effective, a joined and common solution to the Syria problem."
"The bloodshed has to be stopped and this is what we called for. This can be achieved only by political and diplomatic means".
A chief communique released at the end of the G8 summit states that the UK, US, France, Germany, Italy, Canada, Japan and Russia are "committed to achieving a political solution to the crisis based on a vision for a united, inclusive and democratic Syria".
It endorses plans to restart peace talks in Geneva "as soon as possible" and says that they should begin with both sides agreeing on "a transitional governing body with full executive powers, formed by mutual consent".
The document also says that Syria's public services must be "preserved or restored" under future arrangements, adding: "This includes the military forces and security services".
The endorsement at the G8 summit of political negotiations on Syria's two-year civil war met the goals pursued by President Barack Obama, including ones he discussed with Russian President Vladimir Putin, a senior US administration official has said.

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.
If the body language between Presidents Obama and Putin is anything to go by, this summit has been a disaster.
