This was a big day for the Cabinet and for the Cabinet Secretary. The country’s most senior civil servant glanced round the ornate but modest room dominated by the long oval table around which the senior members of the government would congregate at eleven o’clock precisely.

A big day indeed.

The Cabinet Secretary checked her watch for the hundredth time. Less than an hour to go. Was it only 100 days since that fateful election day in June? Only 100 days since Mrs May suffered that shockingly unexpected defeat. One hundred days since Her Majesty had invited Jeremy Corbyn to become her 15th Prime Minister.

And more than a hundred dramas.
