Susanna Reid appeared perplexed on today's Good Morning Britain as a clip was shown of the Prime Minister being questioned about a treehouse.
Speaking to co-host Adil Ray, Susanna explained that there have been reports of Mr Johnson wanting to build a treehouse for his young son. However, the alleged plans are said to be costing around £150,000 - more than some actual houses cost.
She said: "He was asked about this by ITV News. Let's see what he said." The screen cut to a clip of the Prime Minister having a chat with a reporter.
