Turns out someone did say it yesteday…

Susan Elan Jones (Clwyd South) (Lab):

I pay great tribute to you, Mr Speaker, for the honesty you have shown in saying that you got it wrong on the apartheid issue. I have to confess that once upon a time I stood waving a placard outside the university of Bristol union against someone who was viewed as a very right-wing member of the Federation of Conservative Students. I could not possibly name that person; suffice it to say that I think he looks rather better sat in a green chair and wearing a tie with the flag of South Africa on it.

Mr Speaker:

Yes, I fear it was on 23 October 1986; I remember it only too well. I am grateful to the hon. Lady, I am sure, for reminding me.

Eternally grateful.
