Despite an apparent appeal by the leader of the Harrow Labour group not to bring Corbyn-Smith division to the group, the Labour National Executives, seemingly acting upon a local complaint, have suspended an honest Harrow councillor, well known for her support for Jeremy Corbyn and social justice.
The following public tweets by the Headstone South Cllr Pamela Fitzpatrick are self-explanatory:

I a sitting labour councillor and just received an email to suspend me from the labour group for being rude at a meeting.

No detail is given in my suspension no dates or information about which member I am supposed to have been rude to.

I signed the Cllr letter supporting Corbyn and spoke with him at one of his rallies. https://t.co/ovVQBTqQwP

I tried to stop brexit also but I have been suspended despite being elected councillor. https://t.co/9LVq0pJQKv

Thank you. No MP or other councillors suspended even those retweeting false allegations about Corbyn. https://t.co/yoLFP4NuoZ

Some Labour councillors, mostly in Harrow East, are actively pro Owen Smith and most probably have a needle for Cllr Fitzpatrick.
In contrast with the Labour NEC taking direct action in a local situation, the Tory Party hierarchy has always turned a blind eye to the Tory group leader Cllr Hall’s doings.
