Interserve replaces auditor
Outsourcing group Interserve has ditched Deloitte as its auditor and hired Grant Thornton in its place. FTSE 250-listed Interserve decided to end its 15-year relationship with Big Four auditor Deloitte after a competitive tender. The contract is the latest coup for Grant Thornton, which became the auditor of a FTSE 100 firm for the first time last September, when Sports Direct was promoted to the blue-chip index.
