Yes is the simple answer.
As Mr. Scarpaleggia has pointed out, a number of previous governments...and I'm not here to point the finger backwards today, but we've promised more than we've delivered to date. What we need is not only targets but a clear process for planning at regular intervals. If we try to do it on a weekly or monthly basis, we'll be bogged down in red tape. If we try to do it on a 15, 20, 30, or 40-year basis, and say it would be nice to get to 2050, that would be unrealistic. It has seemed to many, and I would agree, that five-year planning intervals seem like a reasonable compromise in terms of staying focused and providing for flexibility in the interim periods.
