"So... the Ambassador was passing intel to the ISA, and the Helghast found out about it. Could be why they decided to end his 'immunity'. Or maybe there's more to it than that..."

MILITARY INTELLIGENCE REPORT - #KL53U

COMMUNICATIONS BETWEEN AMBASSADOR HARKIN AND THE ISA 

Covert communications continue to flow between Ambassador Harkin and the ISA outside of permitted diplomatic channels. 

The first recorded incident was in October 2357, when an encrypted audio message was intercepted by Helghast Intelligence (full transcripts available on request): 

HARKIN: Admiral Grey is still alive — she's being held for interrogation in Kratek's center of operations. I know Kratek — he'll kill her as soon as he has what he wants.. 

Unfortunately the message was not decrypted until after the rescue of Admiral Grey from detention in Diortem

All contact between Harkin and the ISA could have been stopped at this point. However, the decision was taken to allow further communications and monitor them. 

Further transmissions indicated that the ISA were assembling a massive fleet, suggesting that a counter-attack was imminent (September 2358): 

HARKIN: Admiral, I appreciate your warning of the coming storm. But I feel my duty to my nation and to my family is to remain here in Helghan, where my wife and child were born.

Although suspected, confirmation of the ISA's planned invasion accelerated the preparation of our defenses. We were also able to feed misinformation regarding those defenses, ensuring that our Arc Batteries came as a surprise to the ISA fleet (August 2359): 

GREY: ...your words were reassuring, Ambassador. I feel confident that our 'Archangel' will swoop without having its wings clipped.

With the ISA invasion imminent, the Ambassador is judged to outlived his usefulness. However, recent communications regarding asylum for a Helghast defector were brought to the attention of Colonel Kratek. The Colonel has ordered that no action be taken against the Embassy until the defector is confirmed to be inside the building.
