This is absolutely the time for Britain to use its strength and weight insofar as we have it, but I think my hon. Friend is correctly pointing to the complexity of the situation. The whole conflict started with an appalling injustice: the rebel Government, who represent less than 25% of the population, took over the capital Sana’a and ejected a legitimate Government and a president who had been through an election. That is the heart of this conflict. The concern on the coalition side, which is completely legitimate, is that nothing in the peace process ends up legitimising a wholly illegitimate takeover of power.
