§ Mr. Freeman
London Underground tells me that its record consists of four-week periods rather than calendar months. Figures are not yet available for the whole of the four-week period ending 23 June 1990, but from 27 May to 21 June the fire brigade was called to be in attendance at a London underground station on 474 occasions. I also refer the hon. Member to the answer I gave to the hon. Member for Lewisham, Deptford (Ms. Ruddock) on 8 May,Official Report, column 7.
