US war secretary Pete Hegseth was today branded a ‘blustering anchorman’ as he sparked a backlash by mocking the ‘big, bad Royal Navy’.

In the latest American blast at Britain over the Iran war, Mr Hegseth demanded the UK and other countries ‘step up’ to reopen the Strait of Hormuz.

In response to US and Israeli attacks, which began at the end of last month, Iran has effectively closed the crucial sea passage and sent global fuel prices soaring.
