I join the hon. Member for Broxtowe (Mr. Lester) in appealing to the Government to rethink their policy on Cambodia.

With the hon. Gentleman, I recently visited Cambodia for the second time in two years, and I totally agree with what he has said. I would like to ask the Government—this may be the one point on which the hon. Gentleman and I disagree—to challenge the seating at the United Nations when Cambodia is debated on 15 November. That may seem relatively unimportant to us, but it is of great importance to the people of Cambodia because they regard the seat as an important symbol of the world's attitude towards them. It is invidious to have in that seat, as the dominant partner in the coalition, people who represent the Khmer Rouge and who were closely associated with its regime.

Everyone who knows the Khmer Rouge and how it currently thinks, knows that its attitudes have not changed. The people of Cambodia fear that, in some guise, the Khmer Rouge may return. They have great doubts about involving it in any political solution. They believe that they can contain the threat of the Khmer Rouge on the border, but are deeply fearful about the effect of its being allowed back into the country as part of a political settlement.

We know of the desperate need of the country and the fact that it is still isolated by the West. The Leader of the House told me during questions last week that he had no doubt that the Vietnamese have withdrawn from Cambodia. There can be no doubt about the fact that the Vietnamese have not remained as settlers.

We know, too, of Cambodia's desperate need for proper development aid so that the people can improve their infrastructure and their health services and rebuild their country. I cannot stress too strongly their wish to be non-aligned. They do not want to be part of the Eastern bloc. They want to be non-aligned. That is why they do not understand the continuing attitude of the West towards them.

Last week, I put to the Leader of the House, who was answering on the Prime Minister's behalf, a question about an allegation made in Jane's Defence Weekly that the United Kingdom had been training guerrillas over the past four years on the Thailand side of the border in several secret camps. That point was repeated in a film by John Pilger, which was shown last night and in a headline in today's Daily Mirror,Thatcher orders the SAS into Cambodia's killing fields". The Leader of the House said that the Minister would deal with that question in summing up this debate. I hope that he will, because it would be the greatest duplicity for the United Kingdom to be involved in training guerrillas to fight the Government in Phnom Penh having signed a communiqué in Kuala Lumpur on south-east Asia stating clearly that Cambodia must be allowed to decide its destiny free from foreign interference. I should like to have the Minister's assurance on that point.

I thank the hon. Member for Broxtowe for giving me some of his valuable time. The eyes of the world are again on Cambodia and the civil war which persists there. The people are looking to the world, especially Britain because of its past role, to play a constructive part in getting a political settlement and ceasefire. We know the desperate need in that country. Unless we play an active role in trying to bring about a settlement, we too shall be guilty of causing bloodshed in that country.
