He said: “Sinn Féin should be ashamed of themselves.
“The setting of a budget in London that should have been made in Belfast turns back decades of progress to have power on Irish soil.
“While Michelle O’Neill and Gerry Adams can recite slogans around a rights based society, the truth is that Sinn Féin have failed not just for the past ten months, but have failed to deliver over the past ten years.
“The DUP and Sinn Féin institutionalised inequality by failing to deliver language equality, marriage equality and economic equality.
“The past eleven months have continued in the same trend. They aren’t up to the job.
“And while Sinn Féin and the DUP jointly promised they would not abandon the North to British Direct Rule, the betrayal of this promise by Sinn Féin is unforgivable.
“At a time when the government here should be working to protect this island from the chaos of a hard Brexit, Sinn Féin has handed Theresa May a free hand.
“If I was in Sinn Féin I would be embarrassed. Instead of delivering equality, Sinn Féin have gifted Arlene Foster more power than she could have dreamed of.
“They went into two recent elections promising to put manners on Arlene Foster, instead their failed negotiation has handed her and her party complete control.
“They say every political career ends in failure. If the rumours are right, Gerry Adams’ career is going to end in failure.
“This weekend Gerry Adams will walk into his Ard Fhéis having delivered a Tory/DUP government to the people of the North,” added Mr Eastwood.
