i also believe that medical insurance be compulsory for anybody coming to the UK that would stop a lot of health tourism.

Proof of medical insurance already is compulsory for anybody coming to the UK (Including Europe)

if you say so, so say us all ...

If you are a visitor from the European Economic Area (EEA) and you fall ill or have a medical emergency during your temporary stay in England, then you'll need a valid European Health Insurance Card (EHIC) issued by your home country. If you can't show a valid EHIC, you may be charged for your treatment.

[...]

The EHIC is not an alternative to travel insurance. It will not cover any private medical healthcare, being flown back home, or lost or stolen property. Therefore, it is important to have both an EHIC and a valid private travel insurance policy.

[...]

If you do not have an EHIC and cannot obtain a PRC, you may have to pay for treatment at the standard NHS rate.

[...]

If you are coming to England specifically for planned treatment, you will need to make all necessary arrangements yourself in advance. Planned treatment is not covered by the EHIC. If you do not have valid documentation, you may be charged for treatment.

If you are visiting England from a non-EEA country, even if you are a former UK resident, you need to ensure you are covered for healthcare through personal medical or travel insurance for the duration of your visit.

If you need NHS treatment and you have not arranged insurance, you will be charged at 150% of the standard NHS rate, unless an exemption category applies to either you or the treatment.
