Which Minister?

The parliamentary precinct is a funny complex.

There are many floors and many windows that allow people to look from into ministerial offices.

I know of one minister who was observed by a large number of opposition MPs who were having a drink several stories above and opposite the minister. The minister was chatting up a staffer and failed to realise he could be seen. ?

The chatting up process went pretty well and the minister failed to pull the curtains so the opposition MPs got a good look at a minister running one up his staffer.

Apparently there was a sweepstake on how long the minister could last…I believe it was certainly longer than Len Brown
