There was a case, pankhania V London Borough of Hackney (2002). this case involved a description of the property as being let on a monthly licence. however there was evidence that the selling agent new the licence was almost certainly a protected tenancy and the tenant intended to assert it's rights against the buyer. it was held that damages were payable to the buyer as it relied on the misrepresentation in the auction catalogue when bidding for the property.
There is a potential claim but each case turns on its facts and I could not guarantee on the brief facts what are your chances of success if you were to pursue this. a litigation specialist would need to review the documentation and facts to assess your case and chances of success.
