Diane Abbott said she is confident that the Labour Party can win at the next general election, and that she is "looking forward" to a cabinet role.
Speaking at a fringe event at the Labour Party conference, the Hackney MP said she would introduce policies which had a "positive approach" to migrants and refugees should she become Home Secretary.
"I look forward to an election. I believe there's an election around the corner. I believe it's an election we can win," she told delegates at the Stand up to Racism-hosted talk.
"I look forward to being able to implement the positive approach to migration, to refugees and to race in general."
Flanked by anti-Trump and anti-Boris Johnson posters, Ms Abbott continued: "We want to welcome refugees. Particularly child refugees. We don't want to be stigmatising refugees, and we want to fulfil properly our legal and international obligations to people seeking refuge from overseas.
"We don't want a narrative that stigmatises and marginalises migrants."
Her talk came after a speech on the conference's main stage yesterday, in which she slated the Prime Minister and his stance on migration.
"They [Conservative Party] think they can win votes with dog-whistle racism led by Boris Johnson, a man who described veiled Muslim women as letterboxes or bankrobbers, and he has yet to apologise for this," she said.
"They said they would end the hostile environment and end the scandal of Windrush. They have emphatically not ended the sufferings of the victims of Windrush.
"They said they would treat the three million EU migrants in this country fairly. They have not done so, and the situation of EU migrants is a Windrush scandal in the making."
