We read that oil production is in “free fall” in “crisis-hit Venezuela” (Opec cuts – Oil cartel split amid pressure to raise supplies, 22 June). This is not due to maladministration by the Maduro government but because the US is rapidly winding down its Venezuelan oil imports for political reasons. The Trump administration is particularly averse to Venezuela’s attempt to spread the benefits of its primary resource among Venezuelans. The pressure to increase production elsewhere is to help plug the gap in the global supply – made wider by sanctions imposed on Iran.

• Thank you for the heart-breaking supplement (20 June) listing deaths of refugees. It has been placed on the altar of St Roque’s Chapel in St Paul’s episcopal cathedral in Dundee.

• Nina Simone may not have put “more than a dent in the lower end of the pop charts” in America (Report, 20 June), but she had three top five singles in the UK: Ain’t Got No – I Got Life (1968), To Love Somebody (1969) and the reissue of My Baby Just Cares For Me (1985).
