Eagle-eyed shoppers have uncovered a secret message that appears on every Tesco receipt.

So why is it there? And what have Tesco said about it? Here's what you need to know.

What is the story behind why the message is there?

Domestic violence cases have risen by an estimated 20 per cent since the beginning of lockdown.

While the number of cases has spiked nationwide - many victims are still unsure as to what they can do and where to go for help and support.

Since the harrowing figures were released, Tesco have decided to step in and help in the battle against domestic violence.

What does the 'hidden' Tesco receipt message say?

The message - located at the bottom of Tesco's receipts - reads: "Help is available if you're experiencing domestic abuse.

"Call the National Domestic Abuse helpline on 0808 2000 247. Download the Brightsky App."

A Tesco spokesman said: "Domestic abuse affects 1 in 3 women and 1 in 6 men during their lifetime.
