Russian energy giant Gazprom set up shop in London in 1999 and has traded there ever since, but it may quit The City if Britain undergoes a "hard" Brexit that might amputate Gazprom's biggest market.
Russia’s state-run Gazprom may quit London and relocate its trading and marketing operations if a “hard” Brexit denies the energy giant preferential access to EU markets.
Media reports say the company’s most important export market is too valuable to see compromised, and staying in a London outside the EU could see raised barriers and increased costs.

Similar fears of a loss of business with EU nations means several London-based banks and financial institutions are considering relocating parts of their operations.
Gazprom opened its London trading offices in 1999.
