Political stunts can divide voters. One man's poignant moment will send another reaching for the sick bucket.
For what it's worth, I thought the idea of Sarah Brown introducing her husband's speech worked well, giving a human touch to a PM in need of one with many voters even if it does make her more of a public figure.
I'm not sure the PM's aides will be thrilled by the number of mid-speech standing ovations earned by their boss.
The last political leader to receive so many "spontaneous" tributes was Iain Duncan Smith at a Conservative Party conference.
He was gone as leader within weeks.
