1 minister (interior affairs) plus his deputy, as well as the secretary of state.

The point of having a deputy is not to be together, but this reminds me of how much of Polish political and military elite (including the president, a former president, and all chiefs of armed forces) died in a single plane crash in Russia in 2010:

A significant minority of Poles did not believe that it was a tragic accident, as detailed in an official [Russian] report. Instead, they saw the crash at a military airfield near the Russian city of Smolensk as a plot involving Polish and Russian leaders, mid-air explosions and cruel Russians executing survivors. Poland’s Law and Justice (PiS) party turned such theories into political rocket fuel that helped the party sweep to election success in 2015.

Although the disaster killed politicians, military top brass and others from across the political spectrum, it has become a touchstone of PiS’s political identity. It helped the party survive for years in opposition while the country was ruled by the centrist Civic Platform led by Donald Tusk, now the European Council president. The airplane’s wreckage is still in Russia, despite government pledges to get it back to Poland.

With Kaczyński’s encouragement, an entire Smolensk mythology emerged, centering on the idea that the plane crash was no accident. This mythology was cultivated by Kaczyński at monthly vigils in front of the presidential palace in Warsaw — becoming his regular way of communicating directly with his followers. Perched on a stepladder, Kaczyński repeatedly promised to reveal “the truth” about the crash, which he alleged was being covered up by enemies in Poland and abroad.
