First, Sarah Brown told us of her "hero", the Prime Minister. Again and again, it seemed. Then, Samantha Cameron, it was announced, was entering the fray, revealing in a television interview today how her "Dave" makes a terrible mess in the kitchen, but has never let her down.
And so perhaps it was inevitable that Miriam Gonzalez Durantez, the high-flying international lawyer and mother of Nick Clegg's three boys, who had kept a commendably low profile, would join the leaders' wives' rush to the television studios. It was announced yesterday that she will speak publicly in an ITV documentary about her husband, to be broadcast next weekend. Is there no escape?
The interview was expected to take place over the next few days, but sources say she is expected to give a "thoughtful" appraisal of life with Mr Clegg, rather than a chatty insight into household trivia.
Her entry into the frontline of the election came amid signs of a backlash against the decision to expose Mrs Cameron to an interview on ITV, broadcast today, with Sir Trevor McDonald. Former Labour spin-doctor Lance Price told Sky News it was "really rather tacky" for Mrs Cameron to be paraded before the TV cameras when Tory strategists had made a point about her keeping a low profile.
The decision of all three leaders' wives to give public and personal interviews about the three men vying to be prime minister on 6 May has caused a fierce debate about the role of women in modern British politics.
Yvette Cooper, the Secretary of State for Work and Pensions, who is married to fellow cabinet minister Ed Balls, a probable contender for the next Labour leadership, told The Independent on Sunday: "Women will make their judgements about what the party policies are, not about individual personalities or their partners. It will be about what the policies are."
Ms Gonzalez Durantez, who has retained her maiden name, has given only one significant interview since her husband became leader. In a guarded performance two years ago, she revealed how he "very bravely" accompanied her to flamenco classes, "because if you see him dancing [flamenco], you'd realise that it's not something he'd normally attempt". Her decision to return to the spotlight shows that the Lib Dems are not immune to the prevailing wisdom that says voters want to know more about their politicians' lives.
Meanwhile, David Cameron's mother, Mary, has also taken part in the ITV documentary about the Tory leader, recalling details of his upbringing – and his eagerness to be heard. She said: "He always had something to say, even when he was five or six. We went on holiday with another family and they said, 'For heaven's sake, can't you shut David up?'"
