No, as I want to leave some time for the right hon. Member for Leicester East (Keith Vaz) to speak at the end.

We in the SNP have had a very straightforward, honest and consistent position throughout this whole sorry saga: it is simply that this already atrocious humanitarian situation cannot be allowed to get worse through a continued Saudi offensive, and if this Government have any leverage at all, as they claim, with the regime in Riyadh, they must convince it to stop the bombing now and come to the table to bring peace to the people of Yemen.

This debate also provides an opportunity for the London Government to reflect on how their decision to allow arms sales, and how the military and security assistance that they give their Saudi allies, has affected this humanitarian situation. It is a damning indictment of UK foreign policy that we have become so reliant on this one bilateral relationship, not only in terms of the options it gives the UK in the region, but in terms of how important this is to maintain the current level of arms exports.

The stories we have heard today of the humanitarian crisis in Yemen are extremely distressing, and we are hearing ever more harrowing stories from the non-governmental organisations on the ground there trying to help. They come not from just one or two NGOs, but from Save the Children, Oxfam, Amnesty International, the International Committee of the Red Cross and Médecins sans Frontières. They have also come up with plans that all have a similar theme. All these agencies are looking to secure rapid and unimpeded access, to deliver humanitarian aid to the affected populations. They are asking for the current spending and funding commitments to be built upon—a previous speaker talked of the 6% or 7% of funding that has already been given—and for support to be given to the Human Rights Council resolution of September 2016 which calls for an investigation and an international independent inquiry. They are urging all parties to stop the use of explosive weapons with wide area effects on populations, and they are calling for an intensification of efforts to support the UN-led peace talks. Lastly, but most importantly, they are calling for no sales or transfer of arms to any party involved in the Yemeni conflict.

We are also now seeing increasingly desperate tactics employed by Houthi rebels, including the use of unmanned craft to attack Saudi warships in the Red sea, in what is something of a modern warfare first. As I have said, the UK contribution to this is significant, not only in the sense that we have allowed weapons to be exported, but, I believe more significantly, because of the numbers of UK personnel who are advising the Saudi armed forces on a number of issues. What they are doing there is a mystery; it is unclear as the Ministry of Defence refuses to tell us.

When I visited Saudi last year with the Defence Committee, the British embassy was clearly keen to impress upon us that UK personnel were looked on by their Saudi counterparts as playing a vital part—something that gets to the heart of the Government’s narrative—so I would appreciate answers to the following questions. In a war being fought largely by mercenaries, how confident can we be that no current or former UK citizens are involved in ways that would put their actions beyond the purview of the Ministry of Defence? Why have the UK Government stopped trying to buy back the Saudi Government’s undoubted stockpile of cluster munitions, as per their obligations under international law? The issue of cluster munitions sold legally by the UK to Saudi in the 1980s brings to mind the length of the relationship, and I want to reflect on how we got to where we are today.

The UK Government have been involved with Saudi Arabia from the start. UK engineers extracted oil and built roads and infrastructure in the kingdom. UK nurses have staffed the hospitals, and teachers have staffed the schools. How is it, after all that, that the UK has so little leverage over the regime? Why must we always hear about the carrot, not the stick? Germany and the Netherlands have banned the sale of matériel to Saudi on international humanitarian law grounds. Indeed, it is the Government’s rejection of the Dutch-led UN motion on war crimes in favour of the Saudi one that first called their priorities into question. I only hope that it is not the size of the commercial relationship that has skewed priorities in Whitehall.

I have no doubt that the defence sector is important to our national economy, just as it is to the local economy in Fife, but despite the highly skilled jobs and the civilian applications of defence technology, we must consider the high licensing standards that defence products need to conform to in order to be sold worldwide. No one on the SNP Benches does not understand the complex situation. We are expected to believe, on the one hand, that the role that UK personnel play is significant enough to mean that the UK has substantial leverage over the Saudi regime while, on the other hand, that those personnel are not in the country for anything more than an advisory role. I hope that the Minister will take the time to enlighten us today on where those people stand. What is the UK role in Saudi? If it is significant, we are tired of not being given the proper answers. If it is not, please stop telling us we are able to affect matters in the kingdom.

Colleagues have asked other questions today. The right hon. Member for Leicester East is a doughty fighter on Yemen. The hon. Member for Liverpool, West Derby (Stephen Twigg) talked about the 5,000 people who have lost their lives—1,500 of whom were children. The hon. Member for South Ribble (Seema Kennedy) asked about other nations not paying their way, and I am sure that the Minister, with his influence, can bring more pressure to bear on nations that are not putting money into the pot to help Yemen. My hon. Friend the Member for Glasgow Central (Alison Thewliss) mentioned there not being enough independent people to declare that the famine exists and also the £3.3 billion- worth of arms sales, which dwarfs the figure that we offer in international aid.

The hon. Member for Portsmouth South (Mrs Drummond), who always speaks on these matters with great distinction, wants Yemen to return to being a successful, functioning country. That is what we all want, but we must stop the arms sales now to allow space for peace to occur. My hon. Friend the Member for Rutherglen and Hamilton West (Margaret Ferrier) highlighted the £500,000 for children who are suffering from malnutrition. We should cease the arms sales, get on a path to peace, and ensure that the people of Yemen have a fighting chance of rebuilding their country in the future.
