Mumbai: Anti-corruption crusader Anna Hazare on Friday asked Maharashtra government to bring in a strong and effective Lokayukta Bill in the state legislature, failing which he will undertake an agitation.

In a letter to the Chief Minister Prithviraj Chavan, the 75-year-old activist, whose historic 12-day fast in support of a strong Lokpal bill hogged global limelight last year, said Lokayukta should get more powers under the state law.

"When you took over as CM, we thought that you will enact strong laws to curb corruption. On the contrary, corruption has increased in the state," Hazare said.

Maharashtra CM has failed to keep promise on Lokayukta: Anna Hazare, who had written letters to Chavan in July and September last year as well, said the assurance given to him and Medha Patkar on Lokayukta issue was not kept.
