Jeremy Corbyn, the far-left Labor leadership candidate who infamously called Hamas and Hezbollah as his "friends," has been elected leader of the UK's Labor party by a landslide.

The result also crowns Corbyn leader of the opposition, as Labor is Britain's second-largest party. He scooped up nearly 60% of over 400,000 votes cast in the leadership elections, which were announced after his predecessor Ed Miliband resigned following Labor's defeat on May 7.

The controversial MP started off the race as a 200-1 outsider, but shot ahead in the polls as left-wing voters were energized by his radical platform and campaign promises. Many more moderate figures within the party, however, have voiced concern his appointment as head would make the party unelectable for the vast majority of Britons.

Corbyn will now begin to assemble his shadow cabinet, though without several key MPs who prior to the vote said they would not be willing to serve under the left-wing firebrand.

Corbyn's election as head of Britain's opposition will greatly worry many British Jews, the majority of whom have voiced deep concern over his disturbing links to a wide range of extremists, spanning far-right holocaust deniers, an anti-Semitic Christian minister and Islamist terrorist groups.

Those links - as well as his highly controversial leftist economic policies - have drawn criticism from the British Jewish community and senior party figures alike.

In the days before the vote itself Corbyn received an endorsement from Hamas, with the terrorist group hailing him for his "sympathetic" stance towards them.
