SO near and yet so far. Ian Paisley and Gerry Adams are tantalisingly close to "the deal of all deals" which would bring devolved government back to Northern Ireland.

After months of negotiations, the end is in sight. But, after so many false dawns, it comes as no surprise that a successful conclusion remains just out of reach. It seems there is always another obstacle to overcome in Northern Ireland.

To an outsider, the matter of photographic evidence showing the IRA giving up its weapons might seem a triviality, given that the process is to be overseen by General de Chastelain's Independent International Commission on Decommissioning.

But to those on opposite sides of the political divide, it means everything. To Mr Paisley and the DUP, it provides proof that a lifetime of vehement opposition has been worthwhile; to Mr Adams and the IRA, it means avoiding public humiliation.

The delivery of a truly historic deal in time for Christmas would have been a great cause for celebrating peace. It is deeply disappointing that it could not be sealed.

But having come this far, the last step on the journey must, and will, be taken. The DUP and the IRA must find the will to inch over the finishing line in a way which allows both sides to avoid losing face.

Despite all those false dawns, we are confident that it will happen. It may no longer be in time for Christmas, but it remains an enticing prospect for the New Year.
