According to Daily Mail dictionary (modify according to respective nationality)
Ex-pat: 1, A fine upstanding citizen who lives in a Brits-only ghetto, drinks in the Red Lion pub, reads British newspapers, won't eat "that foreign muck" and shouts in English as there's no need to learn the local language. Can often be found on websites bemoaning immigrants' failure to integrate into British society without a hint of irony or self-awareness.
2, The person that knows how the ‘once-Great-Britain’ (© Mail commentators and writers) has gone to the dogs/to hell in a handcart, even though – as they joyfully state in their post – they ‘have escaped to Spain/Australia/ France/New Zealand’ 5 years ago. Such people also bash immigrants without any awareness that they are also immigrants in another country. Littlejohn, writing from Florida, can also be described as an ex-pat (amongst other things).
Ex-pats are remarkably concerned with how British taxpayers money is spent, considering that they no longer pay British tax, or use any services provided by the British Government. They are also remarkably concerned with how often bins are emptied in suburbs across the UK, considering – of course – that they don’t live here anymore. Indeed, readers may often wonder at the acute eyesight and sense of smell that Littlejohn possesses when he so despairingly describes the sights and smells of McBroon’s Britain, perched as he is thousands of miles away in Florida.

Illegal Immigrants.
Illegal Immigrant: A person of non-white appearance, who doesn't speak English, who steals money from the honest, law abiding tax payer, and who gets a million pounds in benefits each day, plus a free house.
And a mobile phone and laptop (that was in a Birmingham BNP leaflet but it was probably in the Mail as well). Immigrants: 1,
plural, Come in one variety only: fraudulent spongers leaching off MY taxes and becoming millionaires while WE work to pay for them. There is no such thing as an immigrant with a life like mine. 2,
singular, A person moving to the UK solely to be ‘showered’ with benefits, receive a free council house and entitlement to ‘yuman rites’. If the immigrant does decide to work they will be stealing a job from a hard-working, dedicated and highly-skilled British worker by working for a pittance. The immigrant will then send every penny of their salary (without paying tax, naturally) back to their relations in whatever rubbish little country they came from.
