I am trying – with limited success – not to panic. Being jammed tight and unable to move in any direction in a crush of hundreds of thousands of flag-waving Argentinian protesters is not for the faint-hearted.

I had come across a loud Buenos Aires demonstration in support of Cristina Kirchner, the left-wing former Argentinian president just convicted of corruption. I followed the drums, the singing and the flags along an increasingly crowded street, foolishly calculating everyone would spread out once we reached the main square.
