Victoria’s parliament has been brought to a standstill after Extinction Rebellion protesters start chanting and holding banners.

Just before 11.30am on Wednesday, parliament was suspended after the protesters unfurled a banner from the gallery saying “Climate emergency, Act Now”.

There was a nine-minute stoppage, before a separate protest caused parliament to come to a standstill for a second time.

Men wearing high-vis shirts with messages directed at Transport Minister Melissa Horne started their own protest.
