UK facing more than 40,000 asylum applications this year as migrants turn to ‘covert methods’, report finds

Britain faces more than 40,000 asylum applications this year as migrants increasingly resort to using “covert” methods to get into European countries, a report has warned.
According to projections by the Overseas Development Institute, the UK will receive around 43,381 asylum applications in 2016, costing over £620 million.
Separate figures show that there were approximately 38,878 asylum claims in 2015.
The think-tank’s report estimates that that 330,000 people will reach Europe this year by sea through “overt” channels, normally across the Mediterranean.
