Millions miss out on seven-day GP access
More than five million people across England are unable to book an appointment with a GP outside of working hours.
BBC analysis of official data shows 10% of registered patients live in areas where there is no access to GPs in evenings and at weekends.
Labour has accused the government of "breaking its promises".
NHS England said it was still on target to provide access to extended care for all patients by 1 October.
