More than 400 small boat migrants have arrived in the first two days of Labour’s returns deal, dashing claims it would be a ‘new deterrent’.

The Home Office confirmed 248 migrants were picked up in the Channel yesterday and brought into Dover.

It followed 155 arrivals on Wednesday – the first operational day of the new Anglo-French treaty.

The Government has refused to disclose how many migrants are being detained for removal to France.

The scheme is also highly likely to face long-running legal challenges.
