An estimated 200 supporters and residents remain on the site, where they have barricaded themselves in
Dean, 29, and Emma, 18, handcuffed themselves to a pole concreted inside the barrel as a human barricade. Lying on mattresses, the pair said they are prepared to stay as "long as it takes"
Dean said: "I have studied what's going on here long and hard and believe when the law is used for wrong, civil disobedience is the only way to oppose it.
"The idea is the bailiffs cannot open this gate without killing us both. We'll sleep here for weeks if we have to"
Looks like #dalefarm is the hashtag Twitter users have settled on...
There's a mixed bag of comment so far on the social networks
Our reporter at the scene says some of the women at Dale Farm threw a party last night - possibly their last ever at the site. Many of the women drank until midnight, listening to music including Rihanna and singing traditional songs.
LATEST: We're starting to get reports of bailiffs gathering at the scene
It seems there has been some sort of delay - we're now being told that bailiffs won't arrive until around 1000
There is a lot of negativity being expressed towards travellers on the social networking sites - it seems the travellers and activists at Dale Farm still have some work to do to win strong public support
Ruth - the woman chained to the car in the picture below - says: "There are people here from all over the world and the travellers have made us so welcome. It has become increasingly difficult for travellers to find a site in recent years. Planning law is very discretionary and we do not feel it's being used fairly."
Our man Ben Kendall is speaking to some of the people holed-up inside Dale Farm
Campaigner Grattan Puxton says: "The gate is closed but talks with the council are going on behind the scenes. The council owes us 62 pitches for those who will be made homeless. We have a High Court hearing at 11am so there is still hope this will pass quietly."
We're starting to get unconfirmed reports that police are closing some of the roads around Dale Farm
But it still seems all quiet inside the farm, according to our man on the ground...
There's a massive media presence at Dale Farm - more journalists than bailiffs so far. But there are rumours that the bailiffs are gathering
Children and adults are climbing the barricades - are we about to see the bailiffs?
This just in from Dale Farm...
