With the help of a policeman and a messenger, she found her way to the tearoom, where Margaret Thatcher was standing by the door waiting for her.

“Come and join me,” she said, before leading her guest to an empty table. “I’ve already ordered tea as I had a feeling you were the kind of person who wouldn’t be late.”

Margaret, as she insisted on Emma calling her, bombarded her with questions about her thoughts on education, the NHS and even Jacques Delors. When Emma asked Margaret, if Ted Heath were to lose the next election and was forced to resign, whether she would consider standing as party leader, she didn’t hesitate in giving her opinion.

“A woman can never hope to be prime minister of this country,” she said without hesitation. “At least not in my lifetime.”

“Perhaps the Americans will show us the way.”

“It will take the Americans even longer to elect a woman president,” said Thatcher. “They are still at heart a frontier society. There are only fifteen women in Congress, and not even one in the Senate.”

“What about the Labour Party?” said Emma. “Some people are suggesting that Shirley Williams—”

“Not a hope. The unions wouldn’t stand for it. They’d never allow a woman to be their general secretary. No, we elected the first Jewish prime minister, and the first bachelor, so we’ll elect the first woman, but not in my lifetime,” Thatcher repeated.

“But other countries have already chosen women to be their PM.”

“Three of them,” said Thatcher.

“So if you can’t be the fourth, and we do win the next election, what job are you hoping to get?”

“It’s not a question of what I’m hoping to get, it’s what Ted will reluctantly offer me. And remember, Emma, in politics it’s never wise to let anyone know what you want. That’s the quickest way to make enemies and detractors. Just look surprised any time anyone offers you anything.” Emma smiled. “So tell me, what’s your brother Giles up to?”

“He’s been put in charge of the marginal seats campaign, so he spends most of his life trudging up and down the country trying to make sure Harold Wilson is returned to No.10.”

“A brilliant choice. He fought and won Bristol Docklands against the odds again and again, and there are many on our side who would have preferred to see him back in the House rather than that second-rater, Alex Fisher. And if Labour were to win, Giles might well become Leader of the Lords, which would see him back in the Cabinet. Anyway, that’s enough politics. Tell me what’s happening in the real world. I see Barrington’s Shipping had another record year.”

“Yes, but I’m beginning to feel I’m repeating myself. It may not be too long before I’m ready to hand over to my son.”
