We describe a president’s term in office as his presidency. As in, “George W Bush’s presidency saw the beginning of the War on Terror.”
How do we describe a prime minister’s term in office? His ministry? His prime ministry? His prime ministership? As in, “During his XXXXXX, Tony Blair became the proud father of a baby…” What do we put in place of XXXXXX?
Also, how do we describe the term in office of a lesser minister, like, say, a Minister of Silly Walks? “During Sir Nigel Tettenbottam’s Ministry of Silly Walks…”?
