Railtrack, BAA and Imperial Chemical Industries are among the more surprising inclusions in the new UK socially responsible investment index launched by FTSE, while Royal Bank of Scotland and Tesco have not met the criteria.

Railtrack's inclusion in the FTSE4Good index series comes despite the Hatfield Report on its poor railway safety record, while BAA has been involved in the controversial Heathrow fifth terminal development and the chemical industry has a poor environmental record in general.
