Australian Prime Minister Tony Abbott is now former Prime Minister Tony Abbott.
Abbott lost his party's leadership vote by 10 votes: 54-44. He will be replaced by his former Communications Minister Malcolm Turnbull.
Turnbull challenged Abbott on Monday, criticizing his economic policy.
"Ultimately, the prime minister has not been capable of providing the economic leadership our country needs," Turnbull told the press.

Friday would have marked Tony Abbott's two-year anniversary as prime minister.
This is the 66th change in Australian party leadership in 13 years.
