- Recruiting more ethnic minority members
- Ensuring the manifesto is ignored by all senior figures and is not drawn up at the last minute
- Establishing clear systems and guidance for candidates and volunteers experiencing abuse

Chief Tory backbencher Nigel Evans said the «stupidity» of the 2017 manifesto convert should never be repeated.
«She had people at Number 10 who were making decisions where in the flesh like ourselves were sidelined,» he told Sky News.
«We really did pay a darned heavy price for that stupidity… We attacked the young and we attacked the old. There was by no means anybody left that we didn’t attack.»
