Former Army officers will visit Downing Street later to demand the option of UK resettlement for all Afghan interpreters who aided British forces.
The UK has offered some interpreters the right to live in the country.
But campaigners will deliver a petition of 27,500 signatures calling for all former interpreters to get that offer.
