It would be difficult for you to write anything on the blog which was against the 'party line', as I'm sure that media people would soon pick up that you blogged. They would certainly watch this space when potentially interesting stories were released through the press office if you were to take that role. It would be a loss for me if you were to be limited by what you thought you could say, and at the same time coming off the 'front line' would, I presume, dilute the experiences that you could write about first hand. The key question however, is what is next for you? If you are content to see yourself doing this for the next 5, 10 etc years, then we will all be delighted for you to keep entertaining us. If not, then we will all understand, I am sure. Why not contact the national sunday papers and see if one of them will offer you a regular column? That would bring some more money in, at the same time as keeping you on the front line. Good luck in whatever you decide.
