Not sure why the UK is included here - the travel ban is:

• has been convicted of a criminal offence in the UK or overseas for which they have received a custodial sentence of 12 months or more
• is a persistent offender who shows a particular disregard for the law
• has committed a criminal offence, or offences, which caused serious harm

Two of those look like something for the Home Secretary to decide, and good luck expecting the Home Secretary to make any sense.
