Thank you, madam. Mr Mayor, is it a fact the London bus fleet is actually cleaner than any other city in Europe and indeed other cities in this country? I am pretty sure I have been told that by TfL in the past. The other thing though, is it not a fact TfL are hastening to retrofit their diesel buses and to introduce hybrids as they will be in Putney High Street in my constituency in this coming year. In fact, 85% of the buses travelling along Putney High Street, which has a pollution problem or has had in the past, 85% will be clean buses?
