The outcome of the research suggests what many might have already supposed - that politicians are just not like other people.
An experiment conducted by the science attraction at-Bristol exposed 25 politicians and 25 regular people to images that also included a lesbian kiss, the BBC's Jeremy Paxman, various barely-clad women and men, a spider and Tony Blair.
The outcome of the research suggests what many might have already supposed - that politicians are just not like other people.
Researchers hooked the MPs up to an emotion detector, showed them the pictures and measured the electric resistance of their skin.
Sweat breaks out
The machine is similar to a lie detector, measuring the sweat that tends to break out when people are stressed or aroused.
Dr Kathy Sykes of at-Bristol, concedes that it may be that the MPs were not actually turned on by the woman many Tories still idolise.
"In a lot of cases it was anger," she said.
But, nevertheless, Dr Sykes was surprised by the results, saying she "was amazed" that so many MPs reacted more to Lady Thatcher than "to Denise van Outen's bare flesh".
"Most people respond to scantily clad images, so why should MPs be any different?"
Not all the politicians got in a lather about Lady Thatcher, however, with 20% reacting more to other images, including one very strong reaction to Mr Paxman.
Although Dr Sykes conceded the research was more about having a bit of fun than conducting a scientific survey, it does indicate that the majority of MPs and their constituents are poles apart.
