Michelle O'Neill says her party is "focused on making the institutions work"
Sinn Féin's leader in Northern Ireland says the DUP's involvement in the Westminster government has complicated power-sharing efforts.
Talks to form a new Stormont Assembly have been ongoing since March, but the parties have yet to reach an agreement.
A number of deadlines have been missed, and the UK's Northern Secretary James Brokenshire has said he will 'reflect' on their next move.
BBC reports Mr Brokenshire will make some financial decisions for Stormont this month - but it will not amount to imposing a budget from parliament.
Michelle O'Neill has blamed the political impasse on the deal between the Conservatives and the DUP.
Speaking in Dublin earlier today, the Sinn Féin leader in the North said: "Part of the reason that we're in this scenario we are, and the political crisis we've reached, is because the DUP have been pandered to by the British government over the last ten years.
"[The government] haven't fulfilled their role as co-guarantor of the Good Friday Agreement. So yet again they've cut a deal with the DUP, all in their own selfless interest."
She added: "We'll see how that works out - but we're focused on making the institutions work."
Ms O'Neill welcomed the 12th of July parades and marching season passing off 'relatively peacefully'.
However, she added: “Sectarian and racist displays at bonfires and the failure of Unionist leaders to challenge this demonstrates the distance yet to be travelled.
“If talks are to be constructive, there needs to be a break from the failures of the past. There can be no return to the status quo that failed so many sections of the community."
