Women bleed onto their white trousers to protest tampon tax outside Houses of Parliament

"CONTENT WARNING: BLOOD," reads the first line of a Facebook post by self-proclaimed "queer Riot Grrrl" Charlie Edge.

Edge stood outside the Houses of Parliament on a dreary Saturday morning, brandishing placards in protest of the "luxury" tax on tampons.

How quickly would we get free tampons if everyone stopped wearing them?

Her Facebook post calls out the five per cent tax rate on sanitary products, saying: "They're not luxury items, anymore than jaffa cakes, edible cake decorations, exotic meats or any other number of things currently not taxed as luxury items."

It's unhygienic

It's such a stupid thing to get upset about

It's gross

I'm sure there's a better way to get your point across

Despite widespread campaigning around the matter and an impassioned speech in parliament from Labour MP Stella Creasy, the tax - which FYI does not apply to edible cake decorations, men's razors or jelly shots - is, for now, here to stay.

Bloody hell.
