London: Britain's data regulator said on Monday that it wants to fine British Airways 183 million pounds over a data breach that compromised information on half a million customers — the biggest to date under new, tougher data regulations.

The airline revealed in September that it had been the victim of a hack. The scam saw customers diverted to a fake website where credit card details were harvested by the attackers.

"People's personal data is just that - personal. When an organization fails to protect it from loss, damage or theft it is more than an inconvenience," Information Commissioner Elizabeth Denham said.
