There were two distinct elements to the demonstrations in Brussels on Monday.
The main bit, with the best part of a thousand tractors squeezing into the centre, was a show of sentiment – a demand to politicians to listen to the demands of farmers.

That was the bit which will get the attention, of course, and observing it was a visceral experience.
The acrid smell of burning tyres and the occasional volley of tear gas from the police.
The drenching rain from above, combined with the countless gallons that flooded streets from the various water cannon dotted around the city.

Time to leave…
