They are the first words uttered by boat migrants to British authorities after they set foot on our soil: 'Where is the hotel?'

It is what they invariably say when they get off buses at the giant migrant reception camp on a former RAF base in Manston, Kent – the centre that processes all who arrive on traffickers' boats.

We know this because, for the first time, whistleblowers at Manston have talked to the Mail in an investigation that lays bare in terrifying detail how overwhelmed staff struggle to adequately process the sheer numbers of migrants arriving on peak crossing days at Manston's doors.

The whistleblowers told us that inadequate checks mean they are powerless to prevent migrants who have criminal pasts from being released on to Britain's streets, and staying in hotels across the country.

'They ask us that hotel question immediately,' a young male worker at the camp said this week. 'They expect to get a hotel bed straight away and that is one key reason they come to the UK. We are told not to answer – to distract them by offering a bag of crisps or a bottle of water.'
