QUES: In 2008, Bloomberg claimed child labour in copper and cobalt mines that supplied Chinese companies in Congo. The children are creuseurs, that is they dig the ore by hand, carry sacks of ores on their backs, and these are then purchased by these companies. Over 60 of Katanga's 75 processing plants are owned by Chinese companies and 90 percent of the region's minerals go to China. An African NGO report claimed 80,000 child labourers under the age of 15, or about 40% of all miners, were supplying ore to Chinese companies in this African region. Amnesty International alleged in 2016 that some cobalt sold by Congo Dongfang Mining was produced by child labor, and that it was being used in lithium-ion batteries powering electric cars and mobile devices worldwide.

QUES: A number of new Presbyterian Churches were founded by Scottish immigrants to England in the 19th century and later. Following the 'Disruption' in 1843 many of those linked to the Church of Scotland eventually joined what became the Presbyterian Church of England in 1876. Some, that is Crown Court (Covent Garden, London), St Andrew's (Stepney, London) and Swallow Street (London), did not join the English denomination, which is why there are Church of Scotland congregations in England such as those at Crown Court, and St Columba's, Pont Street (Knightsbridge) in London. There is also a congregation in the heart of London's financial district called London City Presbyterian Church that is also affiliated with Free Church of Scotland.
