More than 35,000 migrants have crossed the Channel to the UK so far this year. Some 539 people were detected on Monday in 13 boats, the Ministry of Defence (MoD) said, taking the provisional total for the year to 35,233. This is more than the whole of 2021, when 28,561 were recorded.
There have been 2,232 crossings recorded in October so far, PA news agency analysis of Government figures shows.
This includes 1,065 people making the journey on Sunday, marking the fourth time the daily total had topped 1,000 in seven weeks.
Crossings continued on Tuesday amid calm conditions at sea.
The latest milestone comes as the Government faces another legal challenge to its plan to send migrants to Rwanda.
