The son of a toy maker is fighting to stop his half-brother getting his hands on the £14.5 million family fortune after learning he was born out of their mother’s affair.

Stuart Marcus started out selling dolls’ houses from a room above a small east London toy shop in the 1960s before going on to build a multi-million games empire.
