It should give you pause for thought, had Willie Whitelaw done as he was expected, there would have been no Thatcher and while much is made of Thatcher's politics and personality, it is often overlooked that she was Britain's first post war Prime Minister that had played no part in either the 1st or 2nd World War (Wilson volunteered for military service but was classed as a specialist and moved into the civil service).
Those politicians who had served along side the "common man" had difficulty shafting them in civilian life, Thatcher had no such qualms.
Harold Macmillan had served in the First world War....
Volunteering immediately for active service in the War, Macmillan joined the British Army and was commissioned as a temporary second lieutenant in the King's Royal Rifle Corps on 19 November 1914. Promoted to lieutenant on 30 January 1915, he soon transferred to the Grenadier Guards.He fought on the front lines in France, where the casualty rate was known to be high, as was the probability of an "early and violent death". He served with distinction as a captain and was wounded on three occasions. Shot in the right hand and receiving a glancing bullet wound to the head in the Battle of Loos in September 1915, Macmillan was sent to Lennox Gardens in Chelsea for hospital treatment, then joined a reserve battalion at Chelsea Barracks from January to March 1916, until his hand had healed. He then returned to the front lines in France. Leading an advance platoon in the Battle of Flers–Courcelette (part of the Battle of the Somme) in September 1916, he was severely wounded, and lay for ten hours in a slit trench, sometimes feigning death when Germans passed, and reading the classical playwright Aeschylus in the original Greek. The then-Prime Minister Asquith's own son, Raymond Asquith, was a brother officer in Macmillan's regiment, and was killed that month.
Macmillan spent the final two years of the war in hospital undergoing a long series of operations. He was still on crutches on Armistice Day, 11 November 1918. His hip wound took four years to heal completely, and he was left with a slight shuffle to his walk and a limp grip in his right hand from his previous wound, which affected his handwriting

When Harold Macmillan made his maiden speech in the Lords back in the 1980s, aged 90, he said the following...
that the country needed a new industrial revolution that would come about only with intellectual, moral and spiritual revolutions as well.
Speaking of the coal miners' strike, which has lasted for almost nine months and has produced widespread violence on the picket lines, he told the assembled peers:
''It breaks my heart to see - and I cannot interfere - what is happening in our country today. This terrible strike, by the best men in the world, who beat the Kaiser's and Hitler's armies and never gave in. It is pointless and we cannot afford that kind of thing.
''Then there is the growing division of comparative prosperity in the south and an ailing north and Midlands. We used to have battles and rows, but they were quarrels. Now there is a new kind of wicked hatred that has been brought in by different kinds of people.''
Different kinds of people? There was much laughter at this, because the packed House of Lords knew he wasn't referring to Scargill.
