For no particular reason 
... I wonder how many politicians have put pictures of themselves in their underwear online publicly?
It seems very odd to me that someone who says they want to be an MP and later the prime minister would do this. Surely if you were at all politically savvy you'd know this was a bad idea?
I know that some MPs have posed in swimwear- one because she had been a lifeguard & when a paper found old pics she gamely posed again to highlight lifeguards great work.
But in underwear?
