Diplomat quits and says UK ‘could also be complicit in battle crimes’ over arms to Israel

A British diplomat has claimed the Foreign Office “may be complicit in war crimes” over arms sales to Israel in a bombshell resignation note.

Mark Smith, listed as a second secretary in the British embassy in Ireland, dramatically quit – saying members of the Israeli government and military have expressed “open genocidal intent”. Mr Smith added it was “deeply troubling” that the Foreign Office had “disregarded” his concerns on the whether arms sales were legal.

In a letter to colleagues, which has been shared online, he wrote: “It is with sadness that I resign after a long career in the diplomatic service, however I can no longer carry out my duties in the knowledge that this Department may be complicit in war crimes.”

He continued: “Each day we witness clear and unquestionable examples of war crimes and breaches of international humanitarian law in Gaza perpetuated by the state of Israel. Senior members of the Israeli government and military have expressed open genocidal intent, Israeli soldiers take videos deliberately burning, destroying and looting civilian property and openly admit to the rape and torture of prisoners.”

He added: “There is no justification for the UK’s continued arms sales to Israel and yet somehow it continues. I have raised this at every level in the organisation including through an official whistle blowing investigation and received nothing more than ‘thank you we have noted your concern’.

“Ministers claim the UK has one of the most ‘robust and transparent’ arms export licensing regimes in the world, however this is the opposite of the truth.” He concluded the letter: “I hope that we can look back on history and be proud.”

Mr Smith said he had worked on the arms export licensing assessment in the Middle East and North African Department. This makes him a “subject matter expert” on arms sales policy, he wrote.

It comes as pressure mounts on the Government to share the legal advice it’s been given on allowing arms sales. While in opposition Foreign Secretary David Lammy urged the Foreign Office (FCDO) to publish its formal legal advice as to whether Israel was complying with international humanitarian law.

The Government has said it will do so, but not set out a timetable. An FCDO spokesperson said: “This Government is committed to upholding international law. We have made clear that we will not export items if they might be used to commit or facilitate a serious violation of international humanitarian law.

“There is an ongoing review process to assess whether Israel is complying with international humanitarian law, which the Foreign Secretary initiated on day one in office. We will provide an update as soon as that review process has been completed.”

Since 2008, the UK has licensed arms worth more than £576 million to Israel, according to analysis of Government export data by the Campaign Against Arms Trade. In June this year the Government published data on licences granted to Israel since the Hamas attack on Israel on October 7, which showed it had issued 42 licences between October 7 2023 and May 31 2024.

Mr Lammy visited Israel last week alongside French foreign minister Stephane Sejourne, releasing a joint statement on Sunday expressing a “commitment to working ever more closely together in a new spirit of co-operation”. The statement read: “Our visit to a Palestine Red Crescent Society warehouse was a stark reminder of the toll of this conflict, which is unacceptable.

“Without progress towards a ceasefire, this will only worsen. Brave healthcare workers across humanitarian organisations are racing to prevent an all-out polio outbreak but they can only start vaccinating if it’s safe to do so. It’s never too late for peace. An all-out conflict across the region is in nobody’s interests. All parties need to show restraint and invest in diplomacy.”

More than 40,000 Palestinians have been killed since the conflict began, according to local health authorities. Israeli strikes have displaced the vast majority of the territory’s 2.3 million residents and led experts to warn of famine and the outbreak of diseases such as polio.
