US retail giant Amazon will become the UK's largest retailer by 2025, according to reports.

The online giant will overtake supermarket chain Tesco.

Tesco is Britain's biggest grocer and will remain so - but will no longer be the largest retailer in the country within four years.

Amazon’s gross sales are forecast to top £77 billion by 2025.

That is according to new research from Edge Retail Insight.

Tesco’s predicted to have £76.1 billion by 2025.

Tesco's rivals in the supermarket sphere include the likes of budget favourites Lidl and Aldi.

Its traditional rivals are known as the Big Four, and include popular chains ike Sainsbury's, Asda and Morrisons.

“Our data shows that ecommerce is expected to grow in the UK over the next few years, and this will be driven by digital marketplace giants like Amazon, and omnichannel marketplace giants like Tesco,” Edge by Ascential’s chief executive Deren Baker said.

“Over the past year, Amazon has grown its online retail footprint in the UK and expanded into the high street, with the launch of three Amazon Fresh shops in London and a high-tech hair salon, where it can trial technology and product innovation and increase brand presence in the fast-growing beauty sector."

Mr Baker the added in the market share forecast: “This is next-generation retail – Retail 5.0 – marketplaces mastering personalisation at scale. Consumer packaged goods (CPG) brands must focus investment on winning market share through the online platforms most relevant to them.”
