45 pm As my hon. Friend the Minister has already implicitly accepted the precedent for requiring a sinking fund to be made available and for that fund to be placed in the hands of people other than the mining operators, such as the Coal Authority or a river board, I hope that something analogous can be provided, or at least considered sympathetically, so that we have a little pot of gold already in place which can be drawn upon and contributed to by the new coal operators and licence operators as and when a Crisis of Insolvency occurs.
