Dormant Bank and Building Society Accounts Bill [Lords]

My hon. Friend said he had dealt with the last point he raised, but I think the elephant in the room is the voluntary nature of the proposals. There has been scepticism across the House about whether a voluntary scheme can work given that no other voluntary scheme is operating in the world. Will he at this late stage undertake to come to Committee with an amendment that would allow reserve powers to be in the Bill such that at the first triennial review the scheme can be made mandatory if the voluntary system is not working?
