Sextortion criminals | Manchester United v Peterborough | Worst jobs | Goods from Canada, Greenland and Mexico

I was once told by a parent that she shouldn’t have to check her child’s phone because she trusted him. As a police officer, I advise in my presentations on county lines that this is a very dangerous line to take. This is exactly why you should take control of your child’s phone – criminals also believe that children can be trusted (Children in UK as young as 11 targeted by sextortion criminals, data reveals, 9 March).

• Manchester Utd’s new stadium could be delivered in five years (Report, 11 March). By then my beloved Peterborough Utd will be promoted to the Championship, where we will meet the Red Devils following their demotion from the Premier League due to them having no money to buy decent players. A great away day for Posh fans.
