LONDON, Nov 24 (Reuters) - Britain's top share index shed 0.6 percent early on Tuesday as waning risk appetite hit banks, and commodities weakened as the dollar stabilised, while some defensives gained.

At 0911 GMT the FTSE 100 index .FTSE was down 28.94 points at 5,326.56, having finished up 104.09 points, or 2 percent on Monday recording its biggest one-day percentage rise in more than six weeks.

The UK blue chip index is up 20.8 percent this year and has soared more than 50 percent since touching a six-year trough in March, but remains 1.1 percent off levels prior to Lehman Brothers' collapse.
