Dismay as UK gambling reform white paper shelved for fourth time

Delay follows advice to PM that proposals cannot be published until new Conservative leader in place

Proposals to reform gambling laws have been postponed for a fourth time, after advisers to Boris Johnson concluded it could not be published until a new leader of the Conservative party is elected to replace him as prime minister.

Amid a tussle between different Tory party factions over the content of the plans, multiple Whitehall sources told the Guardian that a white paper had been added this week to the government's grid" of announcements and was scheduled to be published on Tuesday.
