Kraft Heinz says it will invest $199m (£140m) in a UK food manufacturing facility over the next four years. The plans for the plant in north west England would see British favourites - ketchup, mayonnaise and salad cream - made in the country once again. It would be the firm's biggest expansion of a manufacturing site outside the US in more than 20 years. The company said it is also one of the largest investments in UK manufacturing since Brexit. The plan, which is subject to approval in the US, will also fund equipment and technology and create up to 50 new full-time jobs, the company said. The Kitt Green plant on the outskirts of Wigan is Europe's largest food manufacturing site, making 1.3 billion cans of food a year. Under the plan, it will start making sauces, as well as continuing to make soups, pasta and baked beans. Heinz sauces were last made in the UK in 1999.
