The handshake of Martin McGuinness and the Queen serves to demonstrate that, in spite of all the political posturing in recent years, John Hume and the SDLP are still writing the script in the northern political sphere.
Long may good relations between Robinson and McGuinness go on. John Hume predicted this was possible at a time when few would dare to agree.
There is a great deal owed to Hume in this process. I would hope that he be honoured with a little bit of gratitude from those following his path to peace.
