It was just approaching 1am this morning when the 27 heads of states finally agreed a text of what is to become the Lisbon Treaty.

The document - which replaces proposals for an EU constitution, abandoned two years ago - aims to make the union run more smoothly now that it has so many more members.
Tensions in the run-up to the deal were clearly running high. I'm told it was thrashed out in a very smoke-filled room. Portugal's smoking ban does not yet seem to have come into force yet.
For once, the British delegation wasn't involved in much of the late-night wrangling, having already secured an agreement on Gordon Brown's "red lines".
As the seven-hour talks continued into the early hours, word was sent to British journos that it was the Italians and Poles that were causing the fuss. No one was trying to unpick our deal.
Heads of state were seen slapping each other on the back and downing champagne at the celebratory drinks afterwards. Gordon Brown appeared to be to the only one without a glass in his hand - perhaps contemplating the difficulties back home.
David Miliband, the UK foreign secretary, is rumoured to have said that he would be adopting a "masochism" strategy in his attempt to sell the document to the British public.
He accused Eurosceptics of "scare stories, myths and navel-gazing".

Looks like the summit is going to finish at lunchtime, as was originally planned. Gordon Brown is set to do his end-of-summit press conference at midday.
11.30am
British officials here are briefing that most of last night's discussions centred on Poland and Italy but Gordon Brown intervened "quite forcefully" on two other issues.
In the first, he moved to stop the European parliament having a veto over the appointment of the president of the commission.
The second was to stop the EU seizing control of data protection.
"It was typical EU bounce and the prime minister intervened quite forcefully to see it off," the official said.
This morning, Mr Brown had breakfast with his Spanish counterpart, Jose Luis Rodriguez Zapatero and then had a meeting with the EU president, Jose Socrates.
11.45am
The suggestion that Tony Blair is being tipped for commission president by
French president, Nicolas Sarkozy, is causing much excitement in the Lisbon press centre.
The claim is buried in an FT article that states: "One new post created by the treaty - that of full-time EU president - will have to be filled in the second half of next year, with Mr Blair being heavily promoted by Mr Sarkozy. The two men dined together in Paris on Wednesday."
British officials say Mr Brown is "relaxed" about the prospect, although few believe Mr Blair would actually want the post. Even if he did, the Iraq factor may make it difficult for him to garner enough support.
Stop press: There is much consternation about whether or not Gordon did in fact have a glass of champagne last night. I've heard two conflicting reports. The question is, is there photographic evidence?
12.45pm
Still waiting for the press conference to begin...
3.15pm
So, almost an hour later than billed, Mr Brown's press conference finally got under way.
"The informal meeting has just finished in the last few minutes," the premier said.
Although dark rings have appeared beneath his eyes - no doubt a result of the late nights and early starts - the PM seemed relaxed and chatty.
The treaty amounted to a great deal, it would mean no more institutional changes for decades and the whole of the EU could now move on to dealing with more important things (my words not his) like climate change, poverty and globalisation.
The premier was twice asked about what is now being termed "champagne-gate". Did he or didn't he allow champagne to pass his lips?
Prudence always uppermost in his mind, Mr Brown confirmed my earlier report - he didn't.
Incidentally, 434KR, I have responded to your question in the comments below.
The prime minister used the press conference to reveal that he and French president Nicolas Sarkozy, his host for tomorrow's Rugby World Cup final, will be both be cheering what he termed as "the European team - England" in the match against South Africa.
Perhaps even less surprisingly, Mr Brown confirmed that the treaty had not brought Britain any closer to joining the euro.
Asked again about the chances of a UK referendum on the treaty, Mr Brown side-stepped an invitation to categorically rule out the prospect but repeated his mantra about the red line opt-outs safeguarding British sovereignty.
On Tony Blair's chances of becoming president of the European Council, Mr Brown insisted his predecessor would be a "great candidate for any significant international job".
And that, as they say, was about all, folks.
