That is the only way to look at MPs these days. They continually spout lies, spin lines, bullshite and bluster, most of it in support of EU agendas (most often hidden in plain sight to the public at least) and present as their own work the implementation of orders and instructions coming from Brussels.
The Bruges Group has ranked Members of Parliament according to their voting in the House of Commons since the 2010 General Election You can check how they voted on the key EU related issues that came before them and see who are the genuine Eurosceptics and who are Europhile. You can also let your Member of Parliament know what you think of their voting record.
Their MP Watch list lists all 650 MPs, which you can sort by MP name, Constituency, Party, Worst/Best, and is worth visiting, to see whether you should be voting for your MP when next they ask for your support.
Green = Eurosceptic, Red = Europhile
So you judge, by what they do, not what they say.
