Probably some truth in that. Much of the research came from the TSR-2.

Weren't Avro working towards a supersonic Vulcan as well?

RAF issued Operational Requirement 330 in 1954 for a supersonic recon
platform which could also be a supersonic V bomber. Most of the British
aircraft manufacturers made submissions but the project was cancelled in
1957. Do a search for the Avro 730, Vickers SP4 (which had 16 engines!),
Handley Page HP.100 and English Electric P.10. Shorts also did a design
but I can't remember what it was called.
