A day before her maiden visit to Uttar Pradesh as the state's Congress General Secretary, Priyanka Gandhi Vadra said that together with the people of the state she hopes to start a "new kind of politics" in which everyone will be a stakeholder.

It especially needs a breakthrough in Uttar Pradesh where the BJP won 71 of the state's 80 seats in 2014.
