Home secretary hits out at 'unacceptable' migrant landings.
Shabana Mahmood told Border Security Command to carry out the review after vessels came ashore at Samphire Hoe, between Dover and Folkestone, on Tuesday, and near Folkestone on Monday.
Twenty-one people were detained on Tuesday after the arrival at Samphire Hoe.
Five people were also detained on Monday, after the uncontrolled landing near Folkestone, the first undetected landing for a year. The Home Office has not said whether more people are being sought.
