This letter-writer to DH says it well (the title means: son of Bangalore's soil, a take on the self-given title of Mr Deve Gowda : son of the soil):
Bangalore Mannina Maga!
Sir, I have been watching the political life of Mr Deve Gowda after he lost the prime ministership and can only pity him. As an ex-prime minister, he is expected to air his comments on international and national issues. On the contrary most of the time his concern seems to be real estate in and around Bangalore, so much so that he crusaded the exit of eminent people from important agencies. The people of Karnataka lost the services of Mr Jayakar Jerome soon after Mr Deve Gowda formed the government with Congress. Now it is Mr Narayana Murthy.
Mr Gowda calls himself a “Mannina Maga”. Does ‘mannu’ refer only to the land in and around Bangalore?
