We had a large group of leftist protesting in front of our Government Building, they were protesting for around 2-3 months, with tents, mobile kitchens, and such. It was hilarious. One of the city’s main boulevards was closed during that period of two months. Also, the right-wingers created their camp, in order to support the previous government, on a different main boulevard. Guess what? The city was blocked for 3 months.
If I am correct even the current PM had slept for a couple of nights in those tents.
I don’t believe that this would happen in the UK. Except if some other higher political power doesn’t ask for the general public to join the “rebellion” .
