Currently sanitary products are taxed at five per cent - while items such as flapjacks have a zero per cent VAT rate.

According to the government's own terminology, a person will pay 20 per cent VAT most of the time "but less on essential items".

Does that mean the chancellor believes all the below things - taxed at zero per cent or exempt altogether - are more essential than tampons?

The Change.org petition says "a five per cent tax rate has been placed on sanitary products, while exotic meats walk tax-free. HM Revenue and Customs justify this rate by labelling these sexual health products as ‘non-essential’ items".

Speaking to i100.co.uk in August, HMRC said the final point was "a matter for ministers".

What's more essential, Mr Osborne, tampons or crocodile meat?
