I don't think he was caught here, the story stands up.
Which story?
Yesterday, a member of JCs team was asked if JC was looking for two seats together, which is why he walked past single empty seats, and the spokesperson said that was "rubbish". That was broadcast last night on mainstream TV.
This morning, JC stated in a press conference that he walked past single empty seats because he wanted to sit with his wife.
Later today, a spokesperson said that he wanted a group of several seats together for him and his team.
JC could have put this to bed yesterday with some savvy PR - but instead, he shouted at reporters last night at his home, argued with a reporter from a leading media outlet at a press conference this morning, and basically he kept the story alive.
His inexperience in dealing with these kinds of situations is showing. He doesn't have the luxury of a probation period in the job, he has to be able to do the job, well, from day 1.
The fact that he's never worked on the front bench, never been exposed to this kind of scrutiny before, and has dismissed staff and colleagues with valuable experience from his team is contributing to the way in which he is coming across.
A man who loses his temper over something so trivial is not really first choice to enter into Brexit negotiations, is he?
