Who got the lowest score ever on Strictly Come Dancing?

The lowest score ever on Strictly Come Dancing is a tie between:

* Ann Widdecombe and Anton du Beke in 2010, who scored a 12 in week 6 for their Salsa.

* Ed Balls and Katya Jones in 2016, who also scored a 12 in week 8 for their American Smooth.

While both couples achieved the lowest score ever, it's important to note that the judging criteria and scoring system have evolved over the years.
