Britain would be reaching a point of no return if it were to ignore EU immigration rules.
According to German paper Der Spiegel, the German Chancellor Angela Merkel is growing frustrated with the Eurosceptic noises coming from the Conservative party.
If Britain were to introduce immigration quotas, as politicians have suggested, this would represent a “point of no return” for Merkel, Der Spiegel says.
The Conservative leadership has come under increasing pressure to swing to the right on Europe, as Ukip gathers support around the country. Indeed, of the 12 new seats Nigel Farage’s has professed to be targeting at the 2015 general elections, 10 are currently conservative seats.
Cameron has also come under pressure from members of his own party. Michael Fallon, the defence secretary said that many UK residents living on the coast feel they are being swamped by immigrants, despite data showing these areas actually have a lesser proportion of non-UK nationals.
