The new rules apply to the whole Liverpool City region, including Wirral, Sefton, Knowsley, St Helens and Halton.
Mr Hancock said, however, the new ban does not include meeting other households in parks or outdoor hospitality venues like beer gardens.
The Health Secretary said: “The rules will be as follows, we recommend against all social mixing between people in different households, m we will bring in regulations as we have in the North East to prevent, in law, social mixing between people in different households in all settings except outdoor public spaces like parks and outdoor hospitality.”
Mr Hancock also announced today that financial support will be provided to the affected areas after stark calls from local authorities.
