Wasps and Sharks aren't Union teams mate, a common mistake - don't worry. London Broncos are your nearest Super League team, whilst Brighton Rugby League are you local team. Hope this helps.
Are you actually asking about a rugby LEAGUE team (because that's a particular type of rugby and the teams you mention play a different one called rugby UNION), or just about the closest Union side? And if so don't feel embarrassed -- many, many people haven't the slightest idea that two forms of rugby exist.
For a start Wasps, Harlequins and Sharks are all rugby sides NOT rugby league teams. There is a rugby league team, the Sussex Merlins at Brighton.
