Who was the Irish prime minister of Israel?

There has never been an Irish prime minister of Israel.

However, William Annyas became the first Jewish mayor in Ireland when he was elected

mayor of Youghal, County Cork, in 1555.

And in 1956, Robert Briscoe became the first Jewish Lord Mayor of Dublin.

==========================================================

Chaim Herzog was the president of Israel, though never the prime minister.

Herzog was born at Clifton Park Avenue in Belfast, Ireland, the son of notable Rabbi

Yitzhak HaLevi Herzog, who was Chief Rabbi of Ireland from 1919 to 1937 (and later,

of Palestone and Israel). The family home (from 1919) was at 33 Bloomfield Avenue,

Portobello in Dublin, Ireland. Herzog studied at Wesley College, Dublin, and was involved

with the Federation of Zionist Youth during his teenage years.
