Could you elaborate on the diverse range of products and services offered by the London Stock Exchange? I'm particularly interested in understanding the types of securities and financial instruments that are traded on the exchange. Additionally, does it provide any specialized services or platforms for investors and market participants? Moreover, I'm also curious to know about the regulatory framework and oversight mechanisms that govern the operations of the London Stock Exchange. Please provide a concise yet comprehensive overview of its offerings.
