Ken Livingstone's suspension from Labour over anti-Semitism has been extended indefinitely pending the outcome of a formal internal investigation.

The former London mayor's suspension from the party had been due to expire on April 27.

But the Huffington Post UK revealed that outgoing Labour general secretary Iain McNicol in his last official act signed off on an indefinite extension of Mr Livingstone's suspension.

A statement from the party said: "Ken Livingstone has been administratively suspended from the Labour Party, pending the outcome of an internal party investigation.

"That suspension starts on the date that his membership suspension applied by the National Constitutional Committee ends on 27 April 2018."
