My Lords, I say to the noble Lord, Lord Bowness, that I have nothing but good will towards him despite our profound disagreements on Brexit.
It has been a pleasure for me in our Committee proceedings up until now to be able to support my noble friend Lady Hayter but, sadly, at this point I have to part company with her. I cannot agree with her or my very good friend the noble Lord, Lord Wigley, that their new clauses are appropriate. They are in effect seeking to substitute the House of Commons for the Government. Under their proposals, the House of Commons would give the Government their marching orders as they move into these negotiations and the Government would be expected to act as an agent of the House of Commons. That is constitutionally inappropriate and will not work well in practice. We saw in the last Parliament the damage done to our national endeavour by the insistence of the House of Commons that it must take charge of the process of negotiation. It was a disaster for us.
When it comes to setting objectives, there is no alternative but to trust the Government. The Government will have to make judgments as they negotiate and the objectives they set for themselves at the beginning may well have to be modified in the light of their assessment of what may be achievable.
I do not think that the analogy the noble Earl, Lord Kinnoull, suggested between the procedures and powers of the European Parliament and the way for us to proceed in our system of parliamentary government is appropriate either.
Openness—the transparency that my noble friend Lord Liddle was calling for—may be difficult, if not inappropriate, in the circumstances of a complex, lengthy and difficult negotiation in which it may not be prudent for the Government to make public what they are thinking of doing and the ways in which they intend to set about it. As the noble Lord, Lord Hamilton of Epsom, reminded us, the House of Commons and your Lordships’ House will have ample opportunities to express their views and to hold the Government to account, not least through the work of the Select Committees of your Lordships’ House.
I support the intention of the noble Lord, Lord Wigley, that the Government should be expected to maintain a full and constructive dialogue and full consultation with the devolved Administrations. We debated that principle yesterday and again in our first debate this morning.
It is very important not only for the benefit of our union—fragile as it is at the moment—but for reasons of practicality and of ensuring that outcome of negotiations makes realistic sense in terms of the situation in Wales, Scotland and Northern Ireland. I would not go as far as the noble Lord, Lord Wigley, or be as prescriptive as him, although I note there is a certain vagueness in the way he has formulated his paragraphs on the requirement for consultation. I think he takes it a bit too far, for the reasons I have given.
There may well be moments in the process of negotiation when the Government consider that it would be helpful and in our interests that they should lay out their position very fully to the House of Commons and seek its endorsement, but that needs to be a tactical judgment in the light of the way events develop. I do not think it is wise for us to seek to tie the Government’s hand and inhibit their freedom in conducting these negotiations as best they can in the interests of our country.
