Russia is aggravating Britain's migrant crisis to overwhelm border defences and sow division in the nation, security sources have claimed.
Vladimir Putin's government is believed to be providing fake documents, transport and even military escorts to smuggling gangs ferrying migrants across the Channel.
The threat overwhelming migration poses to national security is so fierce that this week Nato recognised it by allowing its members to count border protection to spending targets for the first time.
A security source told The Sun: 'Hostile states and malign actors are using illegal migration to test borders, cause disruption and destabilise countries like Britain.
'That's exactly why Nato is now treating border protection as a core part of collective defence — because the lines between traditional military threats and national security are more blurred than ever.'
