UK-based pair behind messaging app accused of giving data to Iranian regime

Exclusive: Branch of Iranian software company TSIT, which makes Gap Messenger, is registered in Sussex

The creators of a messaging app accused of handing user data to the Iranian regime live on a windswept hill in a British coastal town, the Guardian can reveal.

Hadi and Mahdi Anjidani are the cofounders of TS Information Technology, established in 2010 and now registered at the address of a tax accountancy in Shoreham-by-Sea in West Sussex. It is the UK branch of an Iranian software corporation, Towse'e Saman Information Technology (TSIT).
