  • Italy's deputy leaders Matteo Salvini and Luigi Di Maio were thrown together a year ago when they formed a coalition government.
  • Their political backgrounds and priorities differ.

Italy's Labor and Industry Minister and deputy Prime Minister Luigi Di Maio (L) and Italy's Interior Minister and deputy Prime Minister Matteo Salvini (R) wait for the swearing in ceremony of the new government led by Prime Minister Giuseppe Conte at Quirinale Palace in Rome on June 1, 2018.

Italy's deputy leaders Matteo Salvini and Luigi Di Maio were thrown together a year ago when they formed an awkward coalition government, but now their tense alliance seems to be unraveling.

When Salvini and Di Maio — the leaders of the nationalist Lega party and anti-establishment Five Star Movement (M5S), respectively — joined forces and took on the role of deputy prime ministers in a new government (having installed something of a caretaker prime minister in Giuseppe Conte) it was expected that there would be bumps along the way given their ideological differences.
