MPs examining plans for legislation were told 11,500 staff on the contracts, which do not guarantee weekly shifts

The owner of Sports Direct has confirmed that two-thirds of its retail workforce remain on zero-hours contracts ahead of new legislation designed to limit their use.

Frasers Group told MPs who are examining plans to strengthen protections for employees that 11,500 staff were on the contracts, which do not guarantee any weekly working shifts, and did not receive compensation even if shifts were changed at the last minute.
