I accept his statement. But I'm puzzled about why he was sharing hotel rooms (more than once) with Christopher Myers.
If someone's not a family member, and you're not planning to have sex with them, there are only two reasons to share a hotel room with them:
1. Necessity (only one room available at the inn). This sounds implausible. Someone of Hague's position has staff to plan and book his accommodation in advance, and to make alternative arrangements if need be.
2. Economy. Often a very good reason, but surely unlikely in this case. Even in the current age of austerity, we don't think it an unreasonable luxury for our politicians to have their own hotel room. And Hague is a very wealthy man - he could easily afford to pay for separate rooms for Myers and himself out of his own pocket.
Apart from propriety, there's also a very good reason for not sharing a hotel room. Even if you're used to sharing a bed (or a bedroom), you'll both almost certainly get a better night's rest on your own. Even twin beds don't eliminate snoring, talking in your sleep, tossing and turning, getting up to pee and other disturbances for the other person.
So, all rather odd.
