Home Secretary Priti Patel has said that urgent action is needed to stop migrants trying to cross from France to the UK by sea.
Sixty-six suspected migrants were caught crossing the English Channel in small boats on Saturday morning.
It is understood that passengers on board four boats were intercepted by UK authorities amid a fresh wave of attempted sea crossings by migrants.
One of the boats, which was caught by the Border Force and taken to Dover, had 35 people on board, including eight children.
Eight migrants suspected of landing on a beach in Kingsdown in a dinghy, who all presented themselves as Iranian to the authorities, were arrested by Kent Police shortly after they are believed to have disembarked.
Two other boats, one with 16 passengers and the other with seven, were also taken in to Dover by Border Force officials.
