Look ministerial, please

The reporter and I had been given 20 minutes - in total! - to interview and photograph the housing minister in his office. 

I had contacted his department days previously: is there anywhere I can set up some lights? Could I squeeze in an extra five minutes? No, and no. In the end, I had around 20 seconds at the end of the interview - so I sat him down in front of a window and started shooting. 

'Should I smile?' he asked, as his press secretary hovered nervously in the background. 'Could you look ministerial, please,' I replied. His face softened for a moment and we ended up with a half-decent picture.
