UKIP leader Nigel Farage said: "Hardly worth waiting for. It is truly pathetic. No treaty change, no repatriation of powers, no ability to control our own laws, our money or our borders. Now let's get on with the referendum.
"What it means is more Europe with an EU army, EU accession of Turkey, and EU primacy over our laws and our courts.
"Well Cameron wanted a four year ban on migrant benefits, he didn't even ask for a restriction on the open door movement that we have to nearly half a billion people. We can in the first few months or year stop benefits, but from years 2, 3 and 4 bring them up to the current levels. This is pretty weak stuff.
"Fundamental treaty change, which is what the Prime Minister and the Foreign Secretary talked about. A change in our relationship, reform of the European institutions and Donald Tusk, the President of the European Council, in the first sentence of this document says that all the principles on which the European Union was founded have been respected. The treaties stay intact.
"There is no fundamental reform, there's some fiddling around the edges on migrant benefits. I absolutely predict that the effect of this will not be to reduce the numbers coming to Britain but given the huge increase that is coming to a minimum wage, to our living wage, even more people will come.
"I suspect the European Council will approve this document, they are giving us nothing."
UKIP Leader in Northern Ireland David McNarry MLA has said that David Cameron’s EU deal leaves Northern Ireland, the only UK region with a land border with another EU state, exposed. “Sensible people will see that free movement across the Irish border leaves Northern Ireland vulnerable to uncontrolled movement of people, an easy target for illegal migrants and people traffickers.
“David Cameron has agreed to a virtually unworkable system which still sends benefits money to families of EU workers abroad and which doesn’t even put a stop to immediate benefits payable to EU workers, opting instead for a ‘graduated’ system which will still pay some benefits at once. It is a pipe dream to put total reliance on 55% of the other EU countries agreeing with him. He is now their hostage if he agrees to that.”
Thurrock MEP Tim Aker said "The choice couldn't be clearer. We must leave the EU now to regain control of our laws, borders and sovereignty. To stay in risks too much."
