LONDON Almost a quarter of London's rough sleepers are from new EU states, a trend exacerbated by rising unemployment that is reversing a decline in homelessness in the capital, a report says.

Most of those sleeping on the streets come for a better life but many find limited opportunities, and, in some cases, become destitute. While the number of homeless British nationals in the capital has stabilised at about 2,500, citizens of the 10 central and eastern European states account for hundreds more added to the most authoritative tally of rough sleepers. The database Chain, or Combined Homeless and Information Network, which is maintained by Broadway, a homeless charity, on Monday published figures showing that London - the location of more than half of the country's rough sleepers - has almost 4,000 homeless people, a figure up from the 2,500 listed three years ago.

The biggest single factor contributing to growth in the newly homeless is the tiny fraction of 1.5 million migrants who came in search of work from the EU's new border regions but who ended up on the streets as the economy went into a tailspin.

These people are often left to fend for themselves; unless they have worked full-time for a year, migrants from former eastern bloc countries that joined the EU in 2004 and 2007 have no right to public funds and only limited access to services. The outcome is often isolation and homelessness.

British charities say that while the tide of large-scale migration from eastern Europe has largely reversed, many people are staying on thinking there is a only a limited safety net in their own country.

This assertion has been denied by Krzysztof Lisek, a Polish MEP who has helped homeless Poles in the UK. He said that if it were a question of social security then “the migrants would probably choose the Nordic countries”.

Last week during a series of interviews in London where homeless people queued for breakfast provided by charities, many of those on the streets shrugged off the hardships. Most sleep outside, often on church steps. They scavenge at markets because “so much good food is thrown away”, and their days are spent traipsing between shelters or begging; an hour seems to yield a less than a pound.

“You can buy a baguette after a few hours of begging,” said Roman Maciejewski, a 39-year-old former hospital porter from Poznan, west Poland, who arrived this year looking for work but ended up sleeping under a tarpaulin.

Broadway's chief executive, Howard Sinclair, said “The life expectancy of a homeless person on London streets is 42. That is not something that should be happening in 21st century London.”
