The moment being PM dawned on Maypublished at 19:21 British Summer Time 9 May 2017
The One Show have found footage of Philip May at a Conservative Party conference in the 1980s. The pair had a chat about who would go on to stand as an MP.
Mrs May is asked how she felt when it dawned on her that she could be prime minister.
She said its "dawns on you when you're walking through the door of number 10 for the first time".
Philip chips in that "it is very humbling".
