Britain's Labour Party leader Jeremy Corbyn said on Sunday he would stop arms sales to Saudi Arabia for use in Yemen if he wins an election this month.

"Labour will stop arms sales to Saudi Arabia for use in Yemen and work to end the war there, not actively support it as the Conservative government has done," Corbyn said in a speech setting out Labour's foreign policy objectives.

"Labour's new internationalism means we will create a peace and conflict-prevention fund and invest an extra 400 million pounds ($513 million) to expand our diplomatic capacity and increase oversight of arms exports to ensure we're not fuelling conflicts, as in Yemen and in Israel and the Palestinian territories," he said in the speech in the northern English city of York.

The Labour Party also reiterated in an elections policy manifesto its intention to stop selling weapons to Israel if it comes to power.

The reference to Israel was in a document published last Thursday detailing the party’s foreign and defense policies.

“We will immediately suspend the sale of arms to Saudi Arabia for use in Yemen and to Israel for arms used in violation of the human rights of Palestinian civilians, and conduct a root-and-branch reform of our arms exports regime so ministers can never again turn a blind eye to British-made weapons being used to target innocent civilians,” the document stated.
