Who will represent the House of Windsor at the state funeral of Prince Leonard?

Probably Prince Andrew, using it as another excuse to holiday at the taxpayer's expense.

There will be no state funeral for a man who set up his own "principality" and proclaimed himself a prince. The province was never officially recognized as an independent principality.

Prince Charles usually attends funerals, but I doubt he will be attending this one.

He is an usurper so No

Prince George is keen to spread his wings and meet all of his dysfunctional family in person.

He’s not getting a state funeral.

Wow, all these thumbs down even though I’m the only Australian who has answered this question

Given who this man is, I doubt anybody from the British RF will be attending his funeral, state or otherwise!
