Seizures of illegal diazepam double in a year
The number of illegal diazepam tablets seized entering the UK has more than doubled in a year, figures obtained by this programme show.
Some 1.3 million were intercepted in the postal system by the UK's Border Force in 2018, up from 545,000 in 2017.
Doctors warn the authenticity of diazepam bought online cannot be trusted. It is illegal to possess without a prescription.
The medicines regulator said selling such drugs was a "serious offence".
