Boots Group chief executive Richard Baker said the retailer will continue to focus on customer satisfaction and ranging of products in the coming year. He said: 'Trading remains tough and the first few weeks of the new financial year confirms that demand on the high street remains subdued. We have seen nothing to suggest that we need to change our cautious planning assumptions for sales for the full year. Against this background, further progress will take time, but we are making a real difference as we seek to return Boots to sustainable growth.'
