Brazilian Presidential Election - Croke Park

The French Embassy rents the auditorium in Cork City Hall when facilitating elections for French expatriates (the embassy is used in Dublin). There are probably many other examples.

As for Gardai costs, in the normal course of events, the State pays for Gardai security operations outside foreign embassies as the State is duty-bound under the Vienna Convention to protect the integrity of resident diplomatic missions. Just as other countries must protect Irish missions.

In this case - with it being on private property, I'd be confident the Gardai are charging non-public duty fees to the Brazilian embassy if they indeed requested AGS presence. The Gardai would be under no particular duty to protect the integrity of the polling centre unless they were called to an incident. Croke Park doesn't magically become a diplomatic mission protected by the Vienna Convention just because the Brazilian Embassy is renting a function room /hall there.

The brAsiwian election was apparently very close, I’d say the diaspora here swung it. Carnival time I can see ladies on the steps of fine Georgian establishments flashing their wares and twerking in celebration !

Lula's convictions were quashed by the Supreme Court of Brazil - the bench acknowledged that the prosecution and court case was a political stitch-up that paid no heed to rule of law and had no jurisdiction. Not an insignificant point. So no, Lula is not a convicted criminal, it was quashed.

Also wondering where you're pulling these "most Brazilians I know in Ireland" that support Bolsanaro. Your sample size by definition is vanishingly small. Because overwhelmingly, the Brazilian diaspora in Ireland think Bolsonaro is a scumbag democratic-backsliding creep, as evidenced by the first-round results from Ireland.
