Carillion is a disaster on all fronts, but my sympathies go first to the fallen contracting giant’s sub–contractors. Upwards of 30,000 smaller firms were already facing 120-day payment delays and may now have to fight court battles to get paid at all, driving many hard-pressed entrepreneurs to bankruptcy. But the political spotlight won’t help them, because Labour spokesmen who despise small business as well as large will merely use the case to attack the concept of outsourcing public services for private-sector profit.
