Ministers urged to act after US ended support for scheme tracing estimated 20,000 children taken to Russia

The Liberal Democrats are urging ministers to provide replacement UK funding to an American project that locates Ukrainian children kidnapped by Russia, as the party gathers for a spring conference heavily focused on the response to Donald Trump.

British support for the Humanitarian Research Lab at Yale University could be part of a more robust approach towards the US president, particularly over Ukraine, according to Calum Miller, the Lib Dems’ foreign affairs spokesperson.
