With Jane Garvey. Including: With the general election no more than four months away, in our Winning Women's Votes series, Woman's Hour has been looking at issues that might sway the way you vote. We have invited the leaders of the three main parties to come on the programme and we begin with Liberal Democrat leader the Rt Hon Nick Clegg MP, who talks live to Jane in the studio. Last month, launching his party's election campaign, he said: 'The heart of our manifesto will be short, direct and to the point. We have stripped away everything that is not essential because the country cannot afford it'. Jane asks him what will and won't be in his party's manifesto. Last week, many of Mrs Thatcher's personal papers from her first year in office were released and put online. You might think that, as she's a former prime minister, we would be interested in what was going on in her mind as she picked her first cabinet and began to take the reigns of power. But no: the thing that grabbed most press attention was a slip of paper, found inside her personal diary for 1979, on which she had written out a diet consisting mainly of eggs. To take a closer look, Edwina Currie talks about the salmonella scare and Mrs T's egg diet, and Jane is joined by nutritionist Kat McDonald, and chef and food writer Sybil Kapoor, who cooks up some egg recipes. It has been reported that a British woman is among a group of opposition supporters who have been put on trial in Iran for alleged subversive activities. Local reports say the woman, who is 24 and a dual British and Iranian national, faces charges including espionage, participating in anti-government protests, consuming alcohol and having immoral relations with foreigners. She is not believed to be one of the five opposition supporters facing the death penalty, but she is likely to be whipped and imprisoned. The BBC's Tehran correspondent Jon Leyne joins Jane to tell us more.
