Companies will continue to seek new listings despite tough markets, writes Susanna Twidale.

Those already set to join the fray include vending machines group SnackTime and palm oil producer New Britain Palm Oil. If speculation about what is to come proves right, then the rest of 2008's new editions should be just as eclectic.

Already pencilled in are media recruitment group Steppingstone, betting technology group Turftrax and design company investor Designcapital.

Companies which pulled their floats in 2007 due to poor marketing conditions may also chance their arm again if the economic climate improves.

Argentinian restaurant group Gaucho Grill was one such company, who's progress, or lack of, will have been noted by multimillionaire entrepreneur Robert Tchenguiz.

His bar and restaurant company Laurel, which owns the popular Slug and Lettuce, and Ha Ha Bar brands could be poised to float in 2008 with an anticipated market value of around £400 million.

Similarly Cafe Rouge and Strada owner Tragus Group are also thought to be mulling over plans for an IPO.

Richard Branson's gym chain Virgin Active could be joining the market while there could also be a colourful inclusion in the shape of pornography group Private Media Inc.

It is already listed in the US on Nasdaq (PRVT) but is said to have plans to switch to Aim at some point during the year.
