Supermarket giant Tesco has increased its prices on more than 1,000 items meaning shoppers could see a rise during their next weekly shop.
According to MirrorOnline, internal documents seen by PA shows how the retailer has put its prices up by 11% on an average during the first two weeks of this month.
A five-pack of bananas has gone up 11% from 90p to £1; own brand farfalle, macaroni and linguine pasta have all risen 30% from 50p a pack to 65p; seedless strawberry jam is up 23% to 92p and iceberg lettuces are up 17% at 60p each.
The highest price rise was for Merchant Gourmet puy lentils, up from £1.42 to £3.60 a pack - a rise of 152%.
Supermarkets typically move prices on branded products due to promotions coming to an end, but prices on own-brand food and drink tend to be more stable.
But of the top 50 price rises for the supermarket, 18 were own-brand products.
The branded items with the biggest rises include Cathedral City Mild Cheddar up 57% to £5.50 for 550 grams; 20-packs of Carlsberg lager up 33% from £9 to £12; Ferrero Rocher chocolates up from £1 to £1.25 and a 5kg bag of Salaam basmati rice now £9 versus £7 previously - a rise of 29%.

A spokesperson for Tesco said: "Over recent months, cost pressures have continued to build and impact the market.
"We've worked hard to offset these pressures, and focused on protecting our customers for as long as possible. But, like the wider market, we have had to reflect these pressures in the price of some products.
"For the majority of products that have increased in price over the last three weeks, we still beat or match the cheapest of the Big Four [Tesco, Sainsbury's, Asda and Morrisons]."
