The Lords Amendment which is before the House represents a compromise. It was arrived at after a good deal of discussion and conference and, I think, was accepted by all Members of another place as a reasonable compromise in the circumstances. I do not say that everyone was satisfied, but it is in the nature of compromises that most people are not entirely satisfied. Seven years, it was thought, was the minimum period that would be of value in carrying out the purposes of designation. The right hon. Gentleman rightly said that the purpose of designation was one which was accepted. It is to put on notice to the owner of land that his land will probably be required for public purposes within a certain period, and the Minister has to be satisfied that there is a reasonable probability that it will be so required within that period.

The object of the Amendment to the Lords Amendment is to reduce the period of designation to four years, and I submit that it is quite impossible to carry out effective planning if local authorities are enabled to look only four years ahead. It is fortunate that there will not be a great deal of agricultural land that will be the subject of designation, but where it is the subject of designation, it will be important and may involve fairly long-term projects, and if local authorities were limited to four years, the result would be that they could not carry out their planning effectively.

I see all the points which the right hon. Gentleman made about the value of agriculture and the importance of preserving agricultural land, and I think that the Minister, whoever 'he may be, could be safely entrusted to use the powers in the Bill wisely to ensure that not more agricultural land is acquired or is designated than is absolutely necessary; but when it is, I put it to the House that local authorities ought to be able to look ahead for a longer period than four years. I think that seven years is the minimum, and the Government have gone a long way to meet the views of the agricultural industry. For those reasons, I regret that I cannot advise the House to accept the Amendment to the Lords Amendment.
