Two people who came to Britain from Jamaica as children of immigrants invited to plug labor shortfalls after World War II told lawmakers Wednesday how decades later they were wrongly branded illegal immigrants and locked up.

Anthony Bryan and Paulette Wilson are among an unknown number of children of the so-called Windrush generation, named after a ship that sailed from the Caribbean to Britain in 1948, who were wrongly caught up in a crackdown on illegal immigrants.

The resulting political scandal forced the interior minister, Amber Rudd, to resign last month and has raised questions about the record of Prime Minister Theresa May, who as interior minister for six years before Rudd presided over a toughening of immigration policies.
