What silicone/sealant for fitting a glass splashback?

Hi all,

After an advice please. Currently there are ceramic tiles above the cooker and we wish to fit a white glass splashback behind instead (60cm x 50cm). I am confused with regards to what type of silicone to use, read couple of DiY forums and few are saying different things in respect of the silicone/sealant. Can someone please advise what type is the best? It will be sealed to the existing tiles. Having a look on Screwfix website there are lots of different silicones, but is there one especially for this type of job?

Thanks in advance
