We are in a high security wing of Harmondsworth Immigration Removal Centre, just outside Heathrow Airport, to run an advice workshop. Often, we find people with urgent needs for advice and advocacy. But today, almost everyone I see is an asylum-seeker on the Detained Fast Track, which means that there is little that we can do to help.
All the main parties are nervous about the politics of immigration, and figures in YouGov's latest poll for the Sunday Times suggest why. Few of us think that immigrants generally play a positive role in British life. The incessant, and often badly-informed stories, year after year, about crimes committed by black offenders, migrant families who 'jump the housing list' and 'welfare tourists' who come here to hoover up generous benefits - they have taken their toll.
The bottom line is that only 134,000 people - 0.3% of the total population - don't speak English at all. Even in Newham, where well over half the population was born abroad, and the Sun seems to think that people "simply don't want to integrate", fewer than 1 in 10 of the population can't speak English well.
The Ukip policy on the European Convention or ECHR is quite straightforward. We wish to withdraw from this discredited shambles. Why?

The Convention has been used to protect and mother cuddle terrorists, rapists and preachers of hatred.
We are often accused being little Englanders and against immigration per se. We are not. We would happily welcome the brightest and best from around the world, regardless of country, religion or race, but we would not welcome those whose own countries would benefit from their brightest and best staying at home to help build them out of poverty.
