Sir Anwar Pervez and family
Cash and carry
Rank 2017

Pervez came to Britain from Pakistan aged 21 and opened his first shop in 1962. He turned to cash-and-carry in 1966 and his Bestway Group now trades from 62 warehouses under the Bestway and Batleys brands. The London-based conglomerate, which has also developed substantial pharmacy, cement, property and banking services, saw profits surge to £401m in 2015-16. The Pervez family owns just over half, worth £2.75bn, and other wealth adds £200m. Pervez, 82, is a generous donor to charity.
