There is a much better online and interactive rendition of this boundary restriction map by author Alasdair Rae, see: link here. It is based on an OpenStreetMap and freely-available data which is licenced under OGL 3.0, so can be freely used. Thanks as per the talk page for pointing this out.
English: Leicester was made subject to the UK's first 'local lockdown' on 30th June 2020. I made this map courtesy of OpenStreetMap, superimposing publicly available UK government data[1]. It shows the boundary of the local lockdown measures as at that date.
