The BBC’s high profile economics editor, 45, went out with both politicians in the 1990s, when she was in her 20s.
Mr Miliband revealed in July that both he and Mr Balls previously dated the journalist, but insisted that the relationships were “a long time apart”.
The TV journalist said that she hated to see stories about her own past make the headlines. Asked whether she minded when her life became the news, the mother-of-two told the Radio Times: “I hate that. And I’m rather amazed that people should be interested in things that happened a long time ago.
“If people think about their own lives and people that they might have gone out with briefly in their 20s, and what role those people play in their lives now: I think they would realise that it really does not impact on my day-to-day work.”
