As far the refugees seeking asylum in Britain - most of them have made landfall in other countries and thus are economic migrants. Treatment of refugees is subject to UNCR convention of 1951 and the EU Dublin Agreement. In July 2017, the European Court of Justice upheld the Dublin Regulation, declaring that it still stands despite the high influx of 2015, giving EU member states the right to deport migrants to the first country of entry to the EU.
One of the principal aims of the Dublin Regulation is to prevent an applicant from submitting applications in multiple Member States. Another aim is to reduce the number of "orbiting" asylum seekers, who are shuttled from member state to member state. The country in which the asylum seeker first applies for asylum is responsible for either accepting or rejecting the claim, and the seeker may not restart the process in another jurisdiction. This has been clarified several times on this forum yet you still misrepresent it so you can blame the UK.
