The national lottery main game Lotto is to be revamped to boost flagging sales and could see the end of current operator Camelot’s monopoly over the lottery by 2009.

Culture secretary Tessa Jowell is to unveil plans in a White Paper today for different companies to be given the chance to run lottery games. Weekly sales have fallen from a peak of £100m five years ago to £88m now. New licences will cover the main Lotto draw, scratchcards and games accessed over the internet or by mobile phone.

The white paper is to boost public support and make it easier to apply for grants for some of the £14bn already raised for good causes.

Jowell is also expected to recommend a national lottery day and a logo for national lottery-funded buildings to focus attention on national and local lottery projects. And the public will have more input as to which good causes should benefit.

There will also be a new fund of £200m specifically aimed at projects involving young people.
