There's been a bit of chat about this in the past on a food forum. Milbona is a registered trademark of Lidl Stiftung & Co. KG and it's used for various meat and dairy products around the world.
When first asked about the origin of the Turkish Style Yoghurt, Lidl were very cagey but it appears now that it's made in Eire from milk produced in the UK. So, they can get away with claiming that it's a UK produced product.
