1. M&S to shut up shops

Marks & Spencer plans to close 100 shops by 2022 as part of a transformation plan to tackle falling sales and profits.

Fashion chain New Look will close 60 outlets and House of Fraser is planning at least 20 closures, amid tough trading conditions and rising costs in the UK.

2. McD’s doesn’t give a straw

Shareholders at McDonald’s annual meeting rejected a proposal to phase out plastic straws.

The fast-food chain distributes an estimated 95m single-use straws around the world every day, according to consumer advocacy group SumOfUs. Fewer than 8% voted in favour of the proposal. Consumer concern about the effects of plastic pollution has put pressure on the food industry to be more sustainable.
