Shambles at sea

Sir: On 19 July Iranian Republican Guard forces captured the UK flagged tanker Stena Impero, as described by former defence secretary Penny Mordaunt in her Spectator Diary (3 August). It was a national humiliation and it needn’t have happened. As was made clear at the House of Commons Defence Committee hearing on 9 September, warnings were being given about possible Iranian actions as early as mid-June.
