Still 'a lot to do' for EU, Cameron deal

UK Prime Minister David Cameron forged ahead at tougher-than-expected talks with European partners on Friday after meetings through the night failed to make much progress on his demands for a less intrusive European Union.

It's potentially a pivotal moment for the 28-nation bloc, which is proud of its decades of integration among once-enemy nations across Europe. At a tense summit in Brussels, Cameron and other EU leaders staked out firm positions - in part to show voters back home that their interests are being defended.

"We've made some progress, but there's still no deal," Cameron said as he returned for talks just hours after wrapping up meetings at 5:30 am. "We're going to do some more work and I'll do everything I can."
