I would ban women from driving.
I would round up and chuck out all the illegals and asylum-seekers...plus anyone else who demonstrates an unwillingness to adopt the 'traditional' British culture, sense of humour and way of life.
I would ban all forms of religion.
I would instruct all Magistrates and judges to impose maximum fines/punishments for all crimes committed.
I would return prisoners to basic bread and water type diet in a bare cell, with 8 hours rock-breaking each day.
All drug addicts and alcoholics would be forced to go cold-turkey.
All drug-dealers/smugglers would be flogged for first offence and their assets confiscated, given 10 years hard labour for any repeat offence.
All (proven) sex offenders would be castrated.
All (proven) murderers would be executed.
Well, that's a start.
