It strikes me that when things like this happen, all the no name MPs merely see it as an opportunity to 'be infuriated about it' so they can get a mention in the news themselves. It's always the ones who'd turn up to the opening of an envelope that queue up to comment on what was clearly a joke, and actually quite a funny one too
She's clearly got a flair for comedy timing to interject that in the pause of a speech, and has actually gone up in my estimation because of it, not down.
