Broadcaster Mike Parry and ex-Labour MP Stephen Pound are seen spluttering after trying a "disgusting" salty cup of tea.

The pair were testing a theory put forward by an American professor suggesting the perfect tea involves a dash of salt.

"It's foul", a bemused Stephen Pound cried after sipping on the concoction put together by a giggling Andrew Pierce.

Parry and Pound could not conceal their disgust with their faces painting a picture of their emotions after giving the unusual recipe a chance.
