Sainsbury’s is sharpening its funny bone in preparation for this year’s Red Nose Day.

The charitable extravaganza on 13 March will see Comic Relief uniting the country to raise millions of pounds for vulnerable and disadvantaged people in the UK and across Africa.

British designer Lulu Guinness has collaborated exclusively with the supermarket group, which is the official retailer of Red Noses and Red Nose Day merchandise, to create three limited edition bags which went on sale from last Sunday. At least £1.50 from the sale of each £5 bag will go to Comic Relief.

The company has also launched nine new character-themed red noses for £1 each, at least 60p of which will go to charity.

Other products, especially for Comic Relief, include wristbands, pin badges, trolley tokens, air fresheners, Deeley Boppers, slipper bottles, nail wraps, Red Nose stickers, mugs umbrellas and cupcake decoration kits.

Hundreds of well-known brands will contribute to the charitable take in-store, contributing from 5p to £1.25 a product, including, Fairy, Jaffa Cakes, Mr Kipling, Andrex, Gillette, Always and Pedigree.

Sainsbury’s said it had been a supporter of Comic Relief since 1999. It raised £11.5m in 2013 – the last time the fundraising event was held.

Sainsbury’s said it hoped it could make an even bigger different this year.
