The campaign group Refugees for Justice has become part of the community organising charity Citizens UK.
R4J comprises refugees, people seeking asylum and community members demanding justice and change after an asylum seeker was shot dead by police at the Park Inn Hotel in Glasgow in June last year.
Citizens UK said R4J, which has two employees and three consultants, would become a project within its refugee and migrant team.
The move is expected to help R4J expand its reach after it experienced significant growth during its first 12 months of operation.
A spokesperson for Citizens UK said R4J would retain its autonomy while remaining accountable to the trustees and executive team of CUK.
R4J staff will be responsible for delivering its annual plan in accordance with CUK policies and procedures, the spokesperson said.
Dylan Fotoohi, founder and director of Refugees for Justice, said: “Our team is excited to join Citizens UK to work together and make tangible differences to the UK’s asylum seeker system, ensuring tragedies like the one in Glasgow never happen again.”
Matthew Bolton, executive director of Citizens UK, which has 124 staff, said R4J would enrich his organisation by operating as a project with the charity.
