The Foreign Secretary has faced urgent calls to sanction those responsible for the detention of a British man in Dubai for the past 17 years.
MPs and peers have urged David Lammy to publicly call for the release of Ryan Cornelius, now 71, who was detained for 10 years in 2008 as part of a bank fraud case.
The detention was then extended by 20 years in 2018.
A group of 15 parliamentarians, led by Sir Iain Duncan Smith, said the case of Ryan Cornelius was a âflagrant example of arbitrary detention and abuse of powerâ.
A UN working group has found he is subject to arbitrary detention and last week the European Parliament passed a resolution condemning his detention in âinhumane conditionsâ and calling for his âimmediate and unconditional releaseâ.

After the European Parliament resolution, Sir Iain and his colleagues asked Mr Lammy to âimmediately clarify the Governmentâs position on Mr Corneliusâs case and confirm what steps you will now take to press for his releaseâ.
Specifically, they asked whether the Government would make âstrong representations to the UAE on his behalfâ, publicly call for his release and impose âtargetedâ sanctions on those responsible for his detention.
They said: âThe UK has a moral and legal duty to act, as well as a diplomatic responsibility to defend its citizens abroad from such mistreatment.
âWe urge the Government to act with the utmost urgency to secure his release.â
Sir Iain said it was âvitalâ for the Government to take âdecisive actionâ to secure Mr Corneliusâs release.

Foreign Office minister Hamish Falconer has previously said the Government would âcontinue to highlight their concernsâ in talks with the UAE and was providing Mr Cornelius with consular assistance, while it took reports of human rights violations âvery seriouslyâ.
But the UKâs response to his detention has been criticised by Mr Corneliusâs wife Heather and brother-in-law Chris Pagett.
They said: âFor more than 17 years, we have had nothing but defensive waffle from the British Foreign Office.
âThe European Parliament has made a strong and direct call to the UAE for Ryanâs release within months of our taking his case to them.
âThe contrast is shameful. The British people deserve better.â
It is understood that the Government is supporting Mr Corneliusâs application for clemency, and the issue was raised by the Foreign Secretary during a trip to the UAE in December last year.
