Recent BBC story on Hu Jintao incident at China's Congress

Two days ago, BBC reported that there was a mystery and a potential power play by Mr Xi at China's 20th Congress. Given that Mr Hu is not a member of the Politburo's Standing Committee since 2013 and that he was sitting next to Mr Xi and looked confused, I think BBC is way off the mark and a much simpler explanation exists: Mr Hu has dementia and was sitting in the wrong place and was completely lost and had to be escorted away. I am quite surprised at the poor coverage by BBC on this sad non-story.
