A Jewish Labour member was left shocked after someone left a picture of Donald Trump outside her house after she discussed antisemitism at the local constituency party.
Dr Rebecca Moses, who lives in Wimbledon, said she reported the act to the police, as she believed it was a hate crime.
Dr Moses tweeted that whoever placed it there meant to say she was "automatically a Trump fan" because she was Jewish.
Picture of Trump left on my lawn this morning. Ah yes, because I'm Jewish and I spoke about anti-Semitism in the local CLP, I'm automatically a Trump fan. #LabourAntisemitism pic.twitter.com/fmjR2wBlAI

The poster appears to refer to Pete Willsman, the member of Labour's governing body who ranted during one of its meetings about how British Jews were "Trump fanatics" who were making up allegations of antisemitism within Labour.
The JC exposed a recording of his rant in July.
Dr Moses received an outpouring of support after her tweet, including from former Labour leadership candidate Yvette Cooper, who called it "appalling" and sent her "love and solidarity".
Rebecca this is appalling - so sorry you had to deal with this - sending you much love and solidarity

Former Labour councillor Adam Langleben said he was appalled someone had looked up where Dr Moses lived to leave the poster.
He called it "racially motivated bullying of a Jewish Labour member and her family", adding she was brave to speak out.
Someone with records of where Rebecca lives went and did this. This is racially motivated bullying of a Jewish Labour member and her family.

Simon Myerson, a QC, said the intimidation showed how Labour's antisemitism crisis was escalating.
It starts with abuse on social media.

Then people come to your house.
Soon there’ll be violence.
This is how Jew hatred grows.
What are you doing about it? https://t.co/v799u3zPKQ
Dr Moses tweeted that she was "touched by the support I’ve received" since sharing the image.
