Birmingham MP Estelle Morris has expressed regret that her resignation as Education Secretary has done little to change the "macho" world of British politics.
The Yardley MP stepped down from the job in October 2002 in the wake of a series of high-profile problems faced by her department.
The politician, who suffered a daily mauling at the hands of the media, admitted she did not feel she had what it took to manage a large Government department.
In an interview to be broadcast on Teachers' TV tonight, she will highlight David Blunkett's recent resignation as Home Secretary as proof that not much has changed since she left the role.
Ms Morris, who is standing down at the next General Election, said: "We live in a time where politicians are judged by some macho thing about how much they can stand the heat.
"I don't think that is right for democracy. I wish there was a wider debate about the way we do politics in this country. I raised the debate when I left, but there is a bit of me that hoped there would be a difference, a change, and I am not sure I have seen that change yet."
Ms Morris, who is also to step down from her current position as Arts Minister, claimed discussion was still needed on how to tackle the macho culture of British politics.
"I don't want anyone else to resign, but I very much would like to be part of an on-going debate on that," she said.
Ms Morris also called for politicians to be less led by headlines and be more honest with the public.
"It is about showing emotions," she said. "The style of politics I am talking about is about not spinning, not going out with too many journalists to plug stories and not thinking winning is about getting the decent headlines."
Ms Morris quit the job as Education Secretary after it emerged Government targets on literacy and numeracy tests had not been met.
The episode followed swiftly in the wake of two other crisis points under her reign.
In September 2002, thousands of teachers were left unable to start term due to a backlog at the new Criminal Records Bureau which was given the task of vetting new school staff.
Ms Morris faced further criticism over alleged marking down of A-level papers to avoid grade inflation.
Making her resignation speech, she said: "If I'm honest I haven't enjoyed it as much as I did as Minister for Schools Standards. One of the reasons I haven't enjoyed it is it needs a different set of skills."
Many teachers, however, expressed disappointment at losing a politician they considered one of their own because she had been a teacher for 18 years.
During tonight's TV interview by respected educationalist Professor Ted Wragg, Ms Morris also gives an insight into the male-orientated world of Whitehall.
"I was going to do politics my way," she said about taking on the job as Secretary of State for Education.
"I was going to run that department my way with an open door. If there are many around Whitehall for whom that becomes a sign of political weakness then maybe that is a sign of politics."
The interview with Ms Morris will be broadcast at 9pm tonight.
