'Pound still very vulnerable'
BBC Radio 4
The pound is holding gains made since yesterday. A short while ago it was trading at $1.2126.
However analysts say prepare for volatility.
"By and large the pound is still very, very vulnerable. We've seen that the rallies in the pound, since the EU referendum in June, have been very weak, with the declines very prolonged," said Kathleen Brooks, Research Director at City Index.
