Retail stocks have fallen sharply after warnings from Walmart and DIY retailer Wickes hit investor confidence.
US giant Walmart downgraded its profits guidance due to the impact of higher prices on non-food sales, while Wickes cut profits guidance amid signs of a slower DIY market.
In other updates, Marmite maker Unilever reported better-than-expeted sales growth of 8.1% for the first half of the year as higher prices offset a 1.6% fall in volumes.
