Apparently, the polymer used to manufacture some British banknotes is made with fat from cows. This has outraged Hindus worldwide since the “cow, the seat of many deities, is sacred”.

Such is the Hindu consternation at this flagrant act of bovine desecration, that Justin Welby, whose efforts at Dethroning Mammon even before he knew it was rife with ruminants have clearly made a deeper impression than his efforts to run the Anglican Communion, has been enlisted to expunge the cow, along with its many deities, from the banknote.

Insiders have confided that Welby’s next book will be entitled Debeefing Mammon.

From here:

Hindus worldwide are upset over Bank of England’s blunt decision to continue making £5 and £10 polymer banknotes and introducing polymer £20 note, which reportedly contained traces of tallow, despite the serious concerns raised by the Hindu community.

Zed urged BOE Court of Directors Chair Anthony Habgood and Governor Mark Carney to reconsider the BOE decision and halt the production/circulation of £5, £10 and £20 polymer notes.
Rajan Zed also urged UK Prime Minister Theresa May and Archbishop of Canterbury Justin Welby to intervene.
Products from tallow (rendered form of beef or mutton fat) were reportedly used in the manufacture of the polymer substrate for the £5 and £10 polymer banknotes.
Consumption of beef is highly conflicting to Hindu beliefs and it is certainly banned from entering Hindu religious centers. Cow, the seat of many deities, is sacred and has long been venerated in Hinduism.
