Newly disclosed papers reveal that the UK's diplomatic corps cautioned against British military intervention to overthrow the then Zimbabwean president, the long-serving leader, in 2004, advising it was not considered a "serious option".
Policy papers from the then Prime Minister's government show officials weighed up options on how best to deal with the "remarkably robust" 80-year-old leader, who declined to leave office as the country fell into violence and economic chaos.
Faced with the ruling party winning a 2005 election, and a year after the UK joined a US-led coalition to oust Iraqi leader Saddam Hussein, No 10 asked the Foreign Office in July 2004 to produce potential courses of action.
Diplomats concluded that the UK's strategy to isolate Mugabe and forging an international consensus for change was failing, having not managed to secure support from key African nations, notably the then South African president, the South African leader.
Options outlined in the documents were:
"Our experience shows from Afghanistan, Iraq and Yugoslavia that altering a government and/or its harmful policies is exceedingly difficult from the outside."
The diplomatic assessment dismissed military action as not a "realistic option," and warned that "The only nation for leading such a armed intervention is the UK. No one else (even the US) would be prepared to do so".
It cautioned that military involvement would cause heavy casualties and have "serious consequences" for UK nationals in Zimbabwe.
"Barring a severe human and political catastrophe – resulting in massive violence, significant exodus of refugees, and instability in the region – we assess that no African state would support any attempts to remove Mugabe by force."
The paper continues: "We also believe that any other international ally (including the US) would authorise or participate in military intervention. And there would be no jurisdictional basis for doing so, without an authorising Security Council Resolution, which we would fail to obtain."
Blair's foreign policy adviser, Laurie Lee, warned him that Zimbabwe "will be a significant obstacle" to his plan to use the UK's presidency of the G8 to make 2005 "a pivotal year for Africa". Lee concluded that as military action had been ruled out, "we probably have to accept that we must play the longer game" and re-engage with Mugabe.
Blair appeared to agree, noting: "We must devise a way of revealing the lies and malpractice of Mugabe and Zanu-PF ahead of this election and then afterwards, we could attempt to restart dialogue on the basis of a clear understanding."
The departing ambassador, in his final diplomatic dispatch, had recommended cautious renewed contact with Mugabe, though he understood the Prime Minister "would likely be appalled given all that Mugabe has uttered and perpetrated".
Robert Mugabe was finally deposed in a 2017 coup, at the age of 93. Previous claims that in the early 2000s Blair had tried to pressure the South African president into joining a armed alliance to overthrow Mugabe were strongly denied by the ex-British leader.
