BRITAIN’S “callous” Home Office is threatening to deport two seriously disabled children after their Bangladeshi parents abandoned them with a British family, campaigners warned yesterday as they stepped up their fight to keep the pair in London.

Profoundly deaf siblings Samian and Anisa were visiting distant relatives in Poplar in January 2013 when their parents left during the night.

The 12 and 14-year-olds have been fostered by their mother’s family with the support of local authorities and are attending specialist schools in Wandsworth.
