Good afternoon,

Sir Keir Starmer may well have breathed a sigh of relief last night as the Labour Party’s narrow victory in Batley and Spen was announced. The West Yorkshire constituency’s new MP, Kim Leadbeater, won the by-election with the thinnest of margins, just 323 votes. Nigel Morris, i’s Political Editor, writes on why the election result is far from a triumph for the party’s leader, Keir Starmer. Her new constituents have been talking to Dean Kirby, i’s Northern Correspondent, about their relief that the divisive by-election campaign has now reached its conclusion.

A major study has suggested that school closures during lockdowns have caused “considerable harm” to the physical and mental health of children, with as many as 60 per cent of boys and 47 per cent of girls experiencing anxiety. The analysis, published by University College London, comes as debate continues over whether children should be offered the vaccine.

Adding to their investigation on criminal gangs organising migrant crossings, Cahal Milmoand Dean Kirby write on the deadly smuggling routes they promote on Facebook and the terror of migrants left for dead by people smugglers in the English Channel.
