Slum clearance in White’s Row, Portsea, Portsmouth, in about 1929.
In the early years of the 20th century, Portsea already had a reputation as an area of slums, rife with vice and disease. But little was done until after the First World War.
The issue was brought to a head by the murder of Mary Pelham, a prostitute, in Blossom Alley.
The newspapers focused public attention on the appalling conditions.
In 1929 a huge rehousing scheme started in Portsea.
