THERESA May is facing increasing pressure to review the law on cannabis after a raft of MPs including a former Conservative leader called for reform.

Lord Hague, who led the party between 1997 and 2001, has joined those who have urged a change of approach over the drug.

In an article in today's Daily Telegraph he wrote that the idea it can be 'driven off the streets and out of people's lives by the state is nothing short of deluded'.

Let us know what you think - after the Billy Caldwell case, should the law on cannabis be changed?

His comments came after Health Secretary Jeremy Hunt suggested 'a different way' was needed following widespread outrage over the confiscation of cannabis oil from mother Charlotte Caldwell which she brought for her 12-year-old son Billy, who has acute epilepsy.

After Billy was rushed to Chelsea and Westminster Hospital on Friday night in a critical condition, having suffered multiple seizures, Home Secretary Sajid Javid granted a 20-day emergency licence allowing use of the oil.

On Monday, fellow Tory Crispin Blunt, who chairs the All-Parliamentary Group for Drug Policy Reform, urged the Home Office to 'clear out of the way' and let the Department of Health take control of policy on medical cannabis.

But Prime Minister Theresa May suggested that the Government would look only into the operation of the current system of licences for use in individual cases, rather than reviewing the law more widely.

The Home Office said the Government had no intention of reviewing the drug's classification.

In his article, Lord Hague wrote: "Everyone sitting in a Whitehall conference room needs to recognise that, out there, cannabis is ubiquitous, and issuing orders to the police to defeat its use is about as up-to-date and relevant as asking the Army to recover the Empire.

"This battle is effectively over."

Billy was discharged from hospital early on Monday afternoon, but now Ms Caldwell, 50, from Co Tyrone, wants an urgent review of the law on the substance, which is banned in the UK despite being available in many other countries.

Ms Caldwell credits cannabis oil with keeping the boy's seizures at bay, saying he was seizure-free for more than 300 days while using it, but THC is restricted in the UK.

She demanded a meeting with the Home Secretary and the Health Secretary 'within 24 hours'.

Speaking outside hospital, she said: "The fact that Billy has been discharged is testimony to the effectiveness of the treatment and underlines how vital it is that every child and every single family affected in our country should have immediate access to the very same medication."
