Marina Litvinenko, wife of the former Russian spy Alexander - who died after drinking polonium-laced tea in London in 2006 - says the British government "need to be more serious about protection".

In February Mrs Litvinenko told an inquiry into her husband's death that he acted as a "consultant" to a British intelligence service, being paid 拢2,000 a month. The British Government has made no comment on this.

Speaking to 5 live Afternoon Edition, Mrs Litvinenko said more needed be done to ensure the safety of those who may be in similar circumstances to her husband.

"You need to be very serious when you give protection in your country. These people might be dangerous," she said. "You need to be more serious about this."
