The number of small-boat migrants who have reached Britain since Labour came to power is poised to hit 50,000.
The Home Office confirmed 435 arrived on Saturday – bringing the total since the General Election to 49,516.
Hundreds more arrived at Dover on Sunday, with official figures due to be released on Monday.
It means more than 1,000 migrants have come to the UK since the Government’s ‘one in, one out’ deal with France became operational last Wednesday.
The 50,000 milestone is likely to be hit in the coming days amid ideal weather conditions for crossing the Channel.
Shadow Home Secretary Chris Philp said: ‘Labour cancelled the Rwanda deterrent plan before it started with no replacement and numbers have surged.
‘This year so far has been the worst in history for illegal immigrants crossing the Channel. Labour has lost of control of our borders. Every illegal immigrant needs to be removed immediately upon arrival. But this government is too weak to do that.’
On Sunday, Reform UK leader Nigel Farage posted a video which showed migrants chanting ‘Allahu Akbar’ as they apparently crossed the English Channel.

He said: ‘This is a national security emergency. Allowing these men to invade our country will not end well.’ Last week, Mr Philp accused Sir Keir Starmer of ‘gaslighting the British public’ and making ‘grossly exaggerated’ claims over the new migrant deal.
He said the returns agreement would see only 6 per cent of migrants sent back. The deal is also due to last just ten months.
Speaking about the first detentions under the deal, the Prime Minister warned migrants: ‘If you break the law to enter this country, you will face being sent back.’
Home Secretary Yvette Cooper said ‘every migrant’ will be ‘throwing away their money if they get into a small boat’.
Since the start of this year, a record 26,274 migrants have arrived – up 49 per cent on the same period last year.
Protests against illegal migrants continued across the country at the weekend. Demonstrators gathered outside hotels in Bristol and near Gatwick, West Sussex, which are being used to house asylum seekers.
There was also a rally near two migrant hotels in Bournemouth.
In a separate development, 13 migrants were rescued in northern France after locking themselves inside a refrigerated lorry heading for the UK on Saturday.
