Prime Minister David Cameron said today there are "opportunities" for the UK to seek changes in its relationship with the EU.
Following a summit of EU leaders in Brussels, Mr Cameron said:
We did not stand in the way of the eurozone having a banking union... now there are opportunities for us to seek changes in our [EU] relationship, changes that the British people will be more comfortable with.
They [the eurozone members] want to make changes, and we can ask for changes too.
Though none of the elements of the banking union agreed would directly affect the UK, Mr Cameron highlighted that any changes within the eurozone would ultimately affect the wider EU "of which we are an important part".
Prime Minister David Cameron indicated Britain is ready to step up its support for the Syrian opposition, warning, "Nothing is off the table".
Speaking at the end of an EU leaders summit in Brussels, he said the EU and Britain should be doing everything they can to protect civilians in the country and to help accelerate the transition from President Bashar Assad's regime.
"I think it is very important that we do this", Mr Cameron said.
"I want a very clear message to go out to President Assad that nothing is off the table, that further support, further work, further help with the opposition - who are now better formed, better organised, better co-ordinated - is robustly on the table".
"It is a very difficult situation. There are no easy answers. These things do take time. We have to understand all the complexities", he added.
Prime Minister David Cameron told ITV News Europe Editor James Mates the EU leaders discussed how they could encourage transition in Syria "at the top" - through the United Nations - and help and advise the Syrian opposition forces.
Mr Cameron said they had not discussed the possibility of military intervention during the summit:
They are expected to continue discussions on how to make countries stick to economic targets and on creating a "solidarity fund" to help member states suffering one-off economic shocks.
Prime Minister David Cameron said he will push for "a better deal for Britain in Europe" during the talks.
As he arrived this morning, French President Francois Hollande told reporters, "What I want to do next year, is to make Europe more solid, more strong, a Europe that thinks about everybody and that does not make a spectacle of of its problems".
