Haass talks: Sinn Féin 'have difficulties' but agreement possible 17 December 2013 Last updated at 13:51 Sinn Féin have "a series of difficulties" with draft proposals on flags, parades and the legacy of the Troubles, a senior figure has said. However, Gerry Kelly said it was possible to reach agreement this week if the "political will" was there. The parties are involved in another round of talks, a day after receiving US diplomat Richard Haass's proposals. "We are in this together, we have to come to a conclusion together, we are open for that," said Mr Kelly. His comments were Sinn Féin's first public reaction to the draft proposals drawn up by Dr Haass and his team. On Tuesday, DUP leader Peter Robinson said there would be "steam coming out of my ears" if he thought that the draft document was the final paper. Honourable compromise Mr Kelly said his party had deliberately stayed away from "histrionics." Dr Haass said on Tuesday that he was still hopeful of reaching agreement. The DUP will meet Dr Haass on Tuesday afternoon. Earlier, he met with Alliance and the SDLP. Speaking during a break from the talks, he said a fresh draft document would be given to the parties on Wednesday. SDLP leader Alasdair McDonnell said he believed there was room for "honourable compromise" and that the parties had to move away from "narrow political interest." "What we're looking for is further building onto the foundations that are there," he said. Asked about Mr Robinson's comments, his party colleague Alex Attwood said: "People need to be cautious in the language they use and the tactics they employ." Hard work Alliance Party MP Naomi Long said it was "time for parties to show their mettle." "They have asked Dr Haass to come and chair this process, but it's our process, any agreement has to be our agreement, and we are the elected representatives who will have to see it through," she said. That requires commitment from people - it doesn't require hysteria, grandstanding or game-playing; it requires hard work, and that's what we need to see over the next few days. The discussions are expected to move up a gear on Wednesday, as Dr Haass's team pushes towards an agreed conclusion. The US diplomat returned to Northern Ireland last week for what he said would be an "intense two weeks of deliberations and negotiations."
