Watford capture Williams
The 25-year-old Scotland midfielder has signed a two-and-a-half-year deal with the mighty Horns.
Williams becomes the fifth signing for the club in January, following Moses Ashikodi, Will Hoskins, Lee Williamson and Steve Kabba.
He joined Leicester from Nottingham Forest in 2004, but his contract was set to expire at the end of the season.
