Britain's Labour Party Set for Leadership Battle

In the latest twist in this unpredictable summer of British politics, the embattled leader of the country's opposition Labour Party is finally to face a formal leadership challenge.

Jeremy Corbyn, the far-left member of parliament (MP) who won the party's leadership in a popular revolution last year, will face a challenge by fellow MP Angela Eagle after talks between the party's parliamentary wing and its labour union backers collapsed Saturday.
