Red days are defined as days which the Met Office has assessed as "likely" or "highly likely" to see small boat crossings, based on things like the height of waves, wind speed and rainfall.By publishing the red day figures, the first official release of this kind, the government is suggesting a link between good weather conditions and the level of migrant crossings.

So far this year, 14,812 people have arrived in small boats - up about 40% on the same period last year. Almost 1,200 people arrived on Saturday alone.BBC Verify asked Peter Walsh from the Migration Observatory, based at the University of Oxford, exactly what impact the weather has on Channel crossings.He said it was a factor but other issues, such as the effectiveness of smuggling gangs and the number of people wanting to reach the UK are likely to be more important.

"A migrant's decision to come to the UK by small boat is important and life-changing for them: will they casually drop their plans and decide not to migrate because of a few consecutive days of bad weather? Or will they just wait until the next safe-weather day," he told BBC Verify.While acknowledging that gangs have exploited periods of good weather to increase crossings, a Home Office spokesperson insisted the government is "restoring grip to the broken asylum system it inherited".

"That's why we are giving counter-terror style powers to law enforcement, launching an unprecedented international crackdown on immigration crime and have prevented 9,000 crossings from the French coastline this year alone", the spokesperson said.

Responding to the red day figures, Shadow Home Secretary Chris Philp, said:In a statement, the Border Guard Bangladesh said it had increased patrolling along the border to curb these attempts.

India has not commented on these allegations.While media reports indicate that the recent crackdown includes Rohingya Muslims living in other states too, the situation is particularly tense and complex in Assam, where issues of citizenship and ethnic identity have long dominated politics.

The state, which shares a nearly 300km-long border with Muslim-majority Bangladesh, has seen waves of migration from the neighbouring country as people moved in search of opportunities or fled religious persecution.This has sparked the anxieties of Assamese people, many of whom fear this is bringing in demographic change and taking away resources from locals.
