Pakistani Foreign Minister Ishaq Dar has been designated as the country's deputy prime minister with immediate effect, according to a notification of the cabinet division on Sunday.

After the formation of the new government earlier this year, Dar took the oath as the foreign minister of Pakistan.

The 73-year-old seasoned politician is a member of the senate, or the upper house of the country's parliament, and an important figure of Pakistan Muslim League-Nawaz (PML-N).

He had also served several times in the past as the finance minister of the South Asian country.
