Phillips got a nice little 'celebrity' article in The Sunday Times.
Rightly or wrongly, the media have a big impact on our perceptions of politicians, so it's a case of having to play the game really and accept that if we want power it's got to be someone the media can tolerate. Phillips also represents a break from Corbyn which the party desperately needs to be seen to be done IMO. If Corbyn and McDonnell simply pave the way for their chosen successor, and it sounds like Rebecca Long-Bailey, I fear more of the same as she'll just get painted as 'Corbyn's girl'.
