Coulter, 65, and his sister Jones, 63, run the Stockport jewellery retailer Warren James, which featured in the financial pages in 2011 when it took a stake in Pinewood Shepperton film studios in a move seen as trying to extract a higher price from rival bidder John Whittaker (qv). The operation quietly built up its holding to 26.1% and at the time of the £323m takeover last year of the renamed Pinewood Group its share was worth about £84m. In 2015-16 the jeweller's parent company made nearly £38m profit on £101.3m sales and with £59.2m net assets is valued at £275m. Coulter and Jones received dividends of £120m last year, along with past dividends and £11m net assets in three other businesses.
