SIR - I read Martin Tod's letter about the police headquarters (Chronicle letters, July 3) with great interest and agree with all that he said.

However, he appears to imply that the whole site will be available for affordable/social housing.

Under present planning arrangements this is simply not the case; affordable/social housing will take up only a proportion of the site, while the rest will be available for open market development.

It is this factor which the planning committee and department should address.
