This is denounced, by those seeking to ensure that the UK upholds its international obligations, as disproportionate. Concern is also raised about the treatment of those held in detention and the practice of dawn raiding families, and holding young children in immigration detention centres for long periods of time. The policy of detaining asylum-seeking children was to be abandoned as part of the coalition agreement between the Conservatives and the Liberal Democrats, who formed a government in May 2010. However, in July 2010 the government was accused of back-tracking on this promise after the Immigration Minister Damian Green announced that the plan was to minimise, rather than end, child detention.
