Ana Brnabić, the Speaker of the Serbian Parliament, reportedly lost her temper during a heated debate on the opposition’s proposal to amend the Mining Law and ban lithium mining.

The parliament has been in discussions for four consecutive days, and tensions escalated yesterday when opposition members held up banners reading “You will not dig.” Deputy Aleksandar Jovanović approached Brnabić with a letter, and it’s reported that she lost control and verbally attacked him.
