He was absolutely right.
The UK police should have advised, but not interfered, and they interfered.
You do remember what the incident was about, do you?
An anonymous email was sent to Prince Charles containing information that a disgruntled former employee of the Ocean Club was involved in Madeleine's abduction.
As was proper procedure His Royal Highness's office forwarded that information to the police.
Who in turn with the protocol of Portugal being the lead investigators forwarded the information to the Portuguese authorities for their information.
It will be noted that the information did not comply with the Portuguese chief investigator's theory and caused him a measure of annoyance.

In the evening, while driving, I receive an unidentified phone call, the last straw…A journalist asks me if I want to comment on the subject of the email. Whether due to the difficult day, the raging storm or the fact of driving through rain…I lose my cool. I reply, irritably, without thinking, that the message is of no interest and that it would be better for the English police to occupy themselves with the Portuguese investigation.
Goncalo Amaral So who exactly caused the damage to reputation which apparently led to Amaral being kicked off the case if that is an example of the volatility of the man?
However, Portuguese law is the law in Portugal. It doesn't stop others stepping back in amazement at its vagaries.
