S6W-15722 Liam Kerr: To ask the Scottish Government, regarding the information set out at paragraphs 2.161 and 2.162 on page 59 of its document, A Deposit Return Scheme for Scotland: Full Business Case Stage 1, how it calculated the value of the "Commercial value of advertising space at RVMs" at £26 million; whether it will publish its workings and assumptions for calculating this figure; what its position is on whether the figure will still be accurate in August 2023; what £26 million of benefits from "Commercial value of advertising space at RVMs" being "allocated to society" means; who specifically will receive the £26 million, and, in light of this document being published in May 2019, whether it is now better able to assess who will benefit from commercial advertising on Reverse Vending Machines.
