Labour is demanding assurances that a Conservative councillor suspended over claims he shared Islamophobic comments on social media will not be welcomed back into the party.
Jeff Potts, councillor for Knowle in Solihull, was suspended after sharing Tweets attacking Muslims.
But he appears to have been re-admitted to the party.
Labour MP Khalid Mahmood (Lab Birmingham Perry Barr) demanded the Conservatives kick Coun Potts out permanently.
Mr Mahmood said: "He should not be allowed to return and we need strong assurances from the Tories he will not be let back in.
"The Tories need to demonstrate that they take Islamophobia seriously as they would with any other form of hate crime or discrimination."
Coun Potts appeared to confirm he had been re-admitted when he told the Solihull Observer: "I am a member of the Conservative Party."
He told BirminghamLive he stood by this comment and would not make any further comment.
The Conservative Party press office told BirminghamLive: "As Jeff Potts was suspended by the local party, you will have to approach them for comment."
We have approached party officials in the West Midlands Conservative Party but have not so far received a response.
The Solihull Council website lists him as an independent councillor.
One Tweet shared by Coun Potts showed an image of Germany apparently transformed into an Islamic state, with a Berlin city sign written in Arabic, German Chancellor Angela Merkel wearing a headscarf and the crescent and star image associated with Islam above the Bundestag, the German parliament.
Text accompanying the image read: "Many 'leaders' of Western European Countries treat Islamic Culture as a FACT of Life that Europeans MUST get used to!"
Another Tweet linked to a news report about a rape case, with the words: "The vile rapists were 3 Muslim men (imagine my surprise) and an unnamed boy."
Coun Potts also shared a Tweet about an arrest in Birmingham with the words: "Drug related mmm will wait on the verdict wonder if his name will be a good old fashioned British name."
All the Tweets were originally posted by other people, and re-Tweeted by Coun Potts.
Mr Mahmood said: "Islamophobia is completely unacceptable and detestable, and it should be rightly challenged. Jeff Potts patently promoted views that are peddled by far-right groups which seeks to denigrate Muslims.
"Hateful material shared online can manifest in physical violence by way of anti-Muslim hate crimes, putting individuals and communities at risk.
"Shockingly, rather than expel Potts from the Conservative Party for his actions, the Tories are celebrating them by potentially allowing him back into the national party."
