From the planning documents:
"The proposal involves the relocation of the memorial to Emmeline and Christabel Pankhurst from its existing location in
Victoria Tower Gardens , Westminster to a new site at Regent’s University London, Inner Circle , London , NW1 4NS . The proposals also include the erection of a new memorial sculpture to Emmeline Pankhurst by Angela Conner on Canning Green, Parliament Square
. All three sites are located within the City of Westminster. Victoria Tower Gardens and Canning Green (both Grade II Registered Parks and Gardens) are located within the Westminster Abbey and Parliament Square Conservation Area, whilst Regent’s University London is located within Regent’s Park,
a Grade I Registered Park and Garden and Conservation Area. The existing memorial to Emmeline was unveiled in 1930 and sculpted by A. G. Walker, a well -known artist of public memorials; the memorial to Christabel was added in 1958 -59. The memorial as a whole was statutorily listed Grade II in February 1970; the brief list description can be found in Appendix 1. "
It may be above board - Thorne has apparently been campaigning for a statue to Pankhurst in Parliament square, and the application certainly mentions the erection of a new statue, so it may be that it's not considered possible to have two statues to one individual so close to Parliament, so a choice has to be made. But if that's the case, why not say so?
(Dons tinfoil hat - it is also possible that the Graun is doing its "report extremely selectively thing" and deliberately omitted the detail about the plans for a replacement statue in a much more prominent place. Thorne was a Tory MP, after all, and from the sound of it, had a number of run-ins with John Bercow. As we all know, if the Graun has to choose between women's issues and toeing the "lefty-dude-bro-solidarity" line, they'll go for the latter every time.)
