There are definitely two free-flying birds from Harewood but although they are male and female and consort occasionally, they are unlikely to breed. Apparently, Lee Evans has gone on record as saying that the Wakefield birds (and every other white stork in the last 15 years) are not tickable. I can understand that for the Harewood birds and the Belgian bird at Wakefield but the French bird is a rehab. there is no evidence that this bird was retained in captivity beyond the point when it had been restored to health. It is irrelevant whether it is exhibiting 'wild' migration behaviour because this bird is not a escape or deliberate free-flyer (as with the female from Harewood). In any case, successful breeding will yield one or more genuine wild fledged white storks and no amount of hair-splitting can take that away. OK, this is a case of an accidental reintroduction but it is still that and if we are going to go down the UK400 line then we have to exclude several species that are established breeding birds such as white-tailed sea eagle and cappers, not to mention any English or Scottish red kite. This is not a criticism of Lee Evans or UK400 but just my observations having worked as a volunteer in rehabilitation.
