Lex Greensill avoids UK appearance but pressed for answers Save Share Greensill Capital founder Lex Greensill is under pressure ahead of British parliamentary hearings this week to provide details of his firmâs supply chain finance contracts with Sanjeev Guptaâs GFG Alliance and explain how it used algorithms to set up future receivables programs. Mr Greensill was asked to appear in person at hearings being held by the governmentâs business, energy and industrial strategy committee, which is examining GFGâs Allianceâs Liberty Steel operations. He declined to attend, claiming that the terms of the inquiryâs reference overlapped with an investigation by the UKâs Serious Fraud Office (SFO) into GFG Allianceâs finances and its relationship with Greensill Capital.
