The CSJ proposals, presented to Downing Street on April 15, come as the government prepares its" Help to Save" scheme for small savers. Citing evidence from abroad, the proposal said: "Prize-linked savings have a strong track record of encouraging people to put money aside - even though they often deliver lower returns than mainstream savings products."
