gypsy, traveller and travelling show people site allocation/planning policy - Public forum - Planning Advisory Service (PAS)

We plan to begin Regulation 18 consultation on a new local plan next year with a view to pre-submission publication in Summer/Autumn 2021 and submission in early 2022.  Currently, we have a 2017 accommodation assessment for travellers to inform the preparation of the new plan. Anyone have experience or advice on whether Inspectors are likely to seek a more up-to-date evidence base which takes account of any changes in circumstance - including local considerations around planning permissions/breaches of planning control and emerging case law/practice in the intervening period?
