A kiss is still a kiss... unless it's from Barack Obama

Mwah! The First Lady's first kiss with the man who would be President has been given a schmaltzy memorial.

A new plaque at the site of the historic snog in Chicago is inscribed with a quote from a 2007 magazine interview with Barack Obama.

"On our first date, I treated her to the finest ice cream Baskin-Robbins had to offer, our dinner table doubling as the curb. I kissed her, and it tasted like chocolate."

What if Britain had a saccharine tolerance as high? Where would our political first kisses be commemorated?

It's hard to be precise but we can surmise that David and Samantha Cameron puckered up in Tuscany, where they met on holiday.

Tony and Cherie? We only know the details of her first, first kiss. She revealed in 2005 she had necked a man called Stephen under a railway bridge in Liverpool (much to his bemusement when he read the newspapers the next day).

If anyone can out-passion Barry and Michelle, it's Nick Clegg, who presumably dropped a shoulder pretty soon after meeting his wife Miriam at a Spanish dance class she was giving in Bruges, where they were both students. Ay caramba!
