The Prime Minister has been asked if he believes in God, leading to him to quote from the Psalms. 

Speaking on a beach in Cornwall at the G7 summit, ITV's Robert Peston asked Boris Johnson whether he is now a practising Roman Catholic, having recently married in Westminster Cathedral.

The Prime Minister replied: "I don't discuss these deep issues, certainly not with you".

Peston laughed and followed up by saying that Sir Keir Starmer has said he does not believe in God, and asking whether Mr Johnson did. 

The Prime Minister paused then referenced Psalm 14: "the foolish man has said in his heart there is no God". 

Peston accepted his answer and finished the interview. 

The surrounding verses in the Old Testament speak about how people have rejected God: 

"The fool says in his heart, ‘There is no God.’ They are corrupt, their deeds are vile; there is no one who does good.

"The Lord looks down from heaven on all mankind to see if there are any who understand, any who seek God. All have turned away, all have become corrupt; there is no one who does good, not even one."

The phrase also appears in Psalm 53.
