When Boris wanted electoral reform
In recent weeks Boris Johnson has joined the No forces in trying the thwart the Liberal Democrats in the AV Referendum.
But the journalist Sonia Purnell, who is writing a biography of the Mayor of London - called "Just Boris" - tells me that in his days as an Oxford student in the 1980s, Mr Johnson was a big supporter of electoral reform.
In November 1985, while running for president of the Oxford Union, Mr Johnson spoke in favour of the motion: "This house has had enough of two party politics" he told Union members:
"There are two reasons why we should vote for a vote that counts...There is an overwhelming case for some type of electoral reform, some form of proportional representation.
"What sort of democracy is it where one party can get only 2% less of the vote than another party and end up with 100 fewer seats in the House of Commons?...
"People will point to places like Italy. For them, a change of government is like a minor reshuffle and it works. They have a standard of living higher than ours...
"[First past the post] causes a crude polarity, a Manichean dichotomy and is dividing the nation. The two old big parties are retreating into their heartlands and currying favour by adopting rigid politics...
"The ruthlessness of the current electoral system is forcing out views and opinions which we may not take seriously until it is too late...This motion is no more than a statement of fact - we have had enough of two party politics. The country has shown it in general elections, local elections and by-elections."
"The finale met rapturous applause," Sonia Purnell writes.
Mr Johnson was no doubt currying favour with the large number of SDP supporters in the Union. And his pro-PR speech helped get him elected.
"It was his SDP-ish stance that meant he got the presidency at the second attempt," Sonia Purnell tells me.
Roll on 25 years, and Mr Johnson wrote in his Daily Telegraph column seven weeks ago: "First-past-the-post has served this country well, and served dozens of other countries well."
