Channel crossings: The 'flimsy' dinghies migrants hope will carry them to safety in the UK
Fishermen have described their shock at the conditions of the small boats people are using to attempt to make the dangerous journey across the Channel to the UK.
One fisherman from Kent says many of the boats being used now are poorer quality and designed for one time use.
Charter Skipper Matt Coker said: "I've seen them going along up close and they don't cope with any waves at all very well because the dinghies are so long and so flimsy - they change shape and bend and buckle and the floors break and they would probably puncture the tubes and the dinghy goes down and everyone's in the water.''
Children and a pregnant woman were among 27 people who died while trying to cross the English Channel in a bid to reach the UK on Wednesday.
Just two were rescued from the water. They are currently in a critical condition fighting for their lives in hospital in Calais.
It is the biggest single loss of life in the Channel since records began in 2014, according to The International Organization for Migration.
Mr Johnson announced on Thursday evening he had written to the French president to set out a five-point plan to tackle the migrant crisis.
The five points of the plan are:
Joint patrols on French beaches to prevent boats from entering the English Channel
Deploying more advanced technology, like sensors and radar.
Patrols from both sies in the UK's and France's territorial waters and in the air
Deepening the work of the Joint Intelligence Cell, with better real-time sharing of information to deliver more arrests and prosecutions
Immediate work on a bilateral returns agreement with France, alongside talks to establish a UK-EU returns agreement.
