LONDON (AP) — Britain’s deputy prime minister said Sunday that he told U.S. Vice President JD Vance he was wrong to blame immigration for the death of a university student who was handcuffed as he lay dying from a stab wound.

David Lammy, who is also the justice minister, said he challenged Vance in what he described as a “robust” phone call on Saturday. Lammy and Vance have struck up a friendship, based on their religious beliefs and family backgrounds, even though they come from different sides of the political spectrum.
