Channel 4 has released a first look at Harriet Walter as Margaret Thatcher in its James Graham drama ‘Brian and Margaret.’

The drama, written by Sherwood boss James Graham, sees Walter play former Prime Minister Margaret Thatcher alongside Steve Coogan 's Brian Walden – the late Labour MP-turned-notorious political interviewer. First-look images show Walter transformed as Thatcher, decked out in her signature skirt suit and trademark hairstyle.

Next up in the world of political dramas – and reenactments of real political events – is Channel 4’s Brian and Margaret, based on former Prime Minister Margaret Thatcher’s final television interview.
