Justice Secretary, Robert Buckland, has warned that people who breaches the new lockdown restrictions in England will face steep fines.
Mr Buckland said law enforcement would continue its approach of policing by consent to encourage the public to comply with the four-week lockdown.
Under the rules, people have been told to stay at home and non-essential shops, pubs and gyms ordered to close.
Households are also banned from mixing indoors or in private gardens, unless in a support bubble.
The National Police Chiefs Council has also warned the most serious offenders will face fines.
Doctors have warned patients not to delay in seeking medical advice should they need it during the next month.
