Mark Pears and family
Rank 2017
Pears, 54, took over his family's London-based property empire at the age of 21 after the death of his father Clive, who helped set it up in 1952 with Pears’s grandfather Bernard. Since then the group he runs with his brothers Trevor and David has amassed a vast portfolio including the Coutts bank building on the Strand.
   Through its Telereal Trillium operation William Pears Group owns 8,000 properties across the UK, with a value of about £6bn, and its Talisman Global Asset Management business is worth at least £50m. The most recent accounts of its largest company showed an increase of £40m of net assets in a single year and profits of £93.3m in 2016. Successful investments such as the $100m the family made from the Facebook float take it to £3.14bn.
   The Pears Foundation spent £16.9m last year, including £2.5m for a family centre at the Anna Freud Centre where 48 children whose mental health problems exclude them from mainstream schools will be taught.
