At just 22 months old, little Sam Miliband has said his first political slogan, his father Ed claimed on Wednesday.
And inevitably, the toddler's words - spoken during Miliband's keynote speech to the Labour conference on Tuesday, according to his wife Justine - were "One Nation".
The Labour leader used the One Nation slogan more than 40 times during yesterday's speech and the message certainly appears to have got through to his son.
In a question-and-answer session with Labour delegates in Manchester on Wednesday, Mr Miliband said: "My younger son, Sam, who's not yet two, was watching my speech yesterday on television with his grandma, and my wife told me this story - I don't really know whether it's true, because he can't properly speak.
"My wife claims that after 15 minutes, he suddenly said 'One Nation'. I'm not sure. I think she was trying to make me feel good."
