OTLEY'S MP has raised a Brexit-related health issue during Prime Minister's Questions.

Alex Sobel (Lab, Leeds North West) decided to use his first PMQ to discuss the concerns of one of his constituents who is insulin dependent.

Addressing government minister David Lidington MP - who was standing in for Theresa May - in the House of Commons on Wednesday, February 6 he said: "My constituent Rachel wrote to me saying: 'my husband can't live day to day without insulin.

"'He's trying to build up a supply by putting in prescriptions early, but there are limits to how much he can order and keep and we have no idea how bad this could get. I'm also worrying about my son, who has serious food intolerances. I lie awake at night worrying about it.’

"As the Minister knows 99.5 per cent of insulin used in the UK is made in the EU and that’s the tip of the iceberg.

"The Home Secretary, Foreign Secretary and Leader of the House all say that we need extra time. When will the Government allow our constituents to sleep at night and announce a delay to Article 50?"

Mr Lidington said: "Obviously if there are concerns about a particular case then the relevant Health Minister would be happy to discuss it with the Honourable gentleman.

"My Right Honourable Friend the Health Secretary and his department have been talking to the suppliers of insulin, and other key medicines and treatment, to ensure that supplies will remain available to patients who need them, whatever the outcome of the current Brexit negotiations."

Speaking to the Wharfedale & Aireborough Observer afterwards, Mr Sobel said: "I am pleased to have been able to ask this very poignant question on behalf of Rachel, as not only has this been a difficult situation for her and her family but it speaks to the worries of many of my constituents."
