My hon. Friend raised these issues when I visited Watford and a number of schools there recently. The pay reforms we have introduced over the last two years have given schools greater flexibility to decide how much they can pay a teacher and how quickly pay progresses. Our reforms are providing schools with the discretion they need to address any school-level recruitment and retention problems they may have. However, as my hon. Friend also knows, decisions about the definitions of inner and outer London and the London fringe area are ultimately a matter for the independent School Teachers Review Body.
