Liverpool recorded 600 cases per 100,000 people in the week ending 6 October. The average for England was 74.
The Liverpool City Region includes the local authority districts of Halton, Knowsley, Sefton, St Helens and Wirral, as well as Liverpool.
More clarity on restrictions is expected later, with new curbs to be reviewed after a month.

Under the new system, Tier 3 is expected to involve the tightest restrictions.
