Many reasons why migrants come here rather than stay in other European countries, although thousands do end up staying in other nations.

The number one reason for refugees continuing their journey to the UK is that they have family here and it's reported that covers 50% of cases.

They also may have already learned English and would find it easier to adapt and find work as a result. Also sometimes, for whatever reason, the traffickers they may have paid to get them out have already pre-determined they are going to the UK. These can be pretty dangerous guys, so your not going to argue with them really when everything is at stake.
