Yeah, not sure that ‘optically’ it’s a good move, as it’s a nuanced topic, but she’s talking about illegal immigration, and deportations (removals - I.e those who have been through the asylum system, then the appeals system, and have come to the end of the road, and are then subject to removal).
It’s a tricky part of the migration system, to remove people who have been refused refugee status and then exhausted all their legal options of appeal and dispute. The process takes so long, that people often then have families here, which complicates the situation, and their country of origin could be somewhere so politically unsettled that it’s not feasible to deport them there.
