Former foreign secretary David Miliband has told Andrew Marr he is "on the frontline but not on the frontbench" of politics, and can learn more about politics as MP for South Shields and campaigning over youth employment.

He added he was "keeping a watching brief" on the shadow cabinet, headed by his brother Ed.
