Scottish Labour 's only remaining MP has promised to personally oversee a "zero tolerance" approach to anti-semitism if he is elected deputy leader of UK Labour.
Launching his campaign at his old school, the Wester Hailes Education Centre in Edinburgh, Murray said he was "embarrassed" by the "cancer" of anti-Jewish sentiment in his party.
Murray was re-elected as the Labour MP for Edinburgh South at last month's general election.
A moderate, he famously resigned from Jeremy Corbyn's shadow cabinet and has been a leading critic of the leftward drift of the party.
He is also strongly opposed to Scottish independence and believes Labour should take a robust stance against indyref2 .
At his campaign launch, he said: “We must reach out and listen to every corner of this country and every person in our country.
“Our party can only win by winning support across the whole of the United Kingdom, by building a coalition of all types of people with a variety of interests."
He added: "The Labour Party must care about every single region and nation of this United Kingdom, and I will take responsibility for the party’s approach to how the UK should be governed in a post-Brexit Britain - so that no city, town or community is left behind.”
Over the past few years, Labour has been criticised over the anti-semitic comments made by party members and elected politicians.
The party leadership has been accused of being slow to stamp out the bigotry.
Murray said: “I’m embarrassed about the cancer of antisemitism in our party.
“As deputy leader I will ensure a zero-tolerance approach to bullying, harassment and antisemitism.
“I will take personal responsibility for the grievance and complaints process, and I will be held responsible for enforcing that zero-tolerance approach."
He added: “Never again do I want any Jewish person to feel that they do not have a home in the Labour Party, that they can’t trust us to do the right thing, or that they feel our party would make the country a more dangerous place for them."
