Livni arrest warrant 'UK's biggest mistake' says Peres

Issuing a warrant for the arrest of an Israeli politician is one of the "biggest political mistakes the UK has ever made", Israel's president says.

President Shimon Peres said it was "high time" the British government changed a law allowing courts to grant such warrants.

The arrest warrant for Israeli former Foreign Minister Tzipi Livni has caused huge embarrassment in London.

British ministers have said they will look "urgently" at reforming the law.
