Schumacher will start testing today

Michael Schumacher signed for Mercedes last month ending a three-year retirement.

Michael Schumacher will begin his Formula One comeback today by taking part in GP2 testing sessions in Spain. The seven-time F1 champion, who signed for Mercedes last month, will begin preparations for his return after a three-year retirement with a three-day testing session at the Jerez circuit. The sessions are meant to help develop GP2 cars for the 2011 season. GP2 is a feeder series to F1. GP2 organiser Bruno Michel called the collaboration a "milestone." "Michael's input and advice will be invaluable," Michel said in a statement. "I am confident that his knowledge and unparalleled driving skills will help us to develop a great car for next season."

Meanwhile, Formula One's governing body (FIA) will appeal a French court's decision to overturn a lifetime motor- sport ban they imposed on former Renault team principal Flavio Briatore. FIA president Jean Todt is working to overturn last week's ruling "to ensure the continuing integrity and safety of the sport". * With agencies
