It was a new dawn. Or at least so Tony Blair said, as he emerged from his landslide victory in the 1997 General Election. It’s what he would say, isn’t it?

Still, there was some truth to the claim. It was the end of eighteen years of Conservative rule. Eleven of them had been under the Iron lady, Maggie Thatcher. And whatever her achievements, she had certainly been the most divisive leader since the Second World War, as she made clear by explicitly breaking with the consensus politics that had marked the postwar scene up to her. It was also revealed in the deeply divided reactions to her death in 2013, with tributes from some (including Tony Blair) and celebration (Ding-dong, the witch is dead) from others.

She’d been followed by John Major, in a government marked above all by division within his own party, as well as some blunders. Also marked, however, by one big breakthrough: the beginning of a peace process in Northern Ireland which he couldn’t take through to completion, but which got some momentum behind it all the same.

That’s the theme the episode concludes with, because it fell to Tony Blair’s government to take that process forward. Its work would lead to the Good Friday Agreement of 1998. That would only be possible thanks to the unflagging support of the governments in both Dublin and London and, indeed, in Washington DC.

As well as to the courage and willingness to go out on a limb of an extraordinary woman, the first female Northern Ireland Secretary and someone of outstanding firmness of will combined with willingness to negotiate to anyone she needed to win around. And who was she?

Why, she was Mo Mowlam.
