As voting begins in 51 parliamentary constituencies across seven states for 5th phase of Lok Sabha Elections on Monday, here is a look at top contests.

The fifth phase of polling in 14 Lok Sabha seats in Uttar Pradesh will see a clash of titans. A number of big political names are facing election today, including Congress chief Rahul Gandhi, his mother Sonia Gandhi and BJP Union ministers Rajnath Singh and Smriti Irani.

The BJP had bagged 12 of these seats in 2014 with the Congress winning Sonia Gandhi's Rae Bareli and Rahul Gandhi's Amethi – the only two constituencies where the Congress succeeded out of the 80 in the entire state.

Union home minister Rajnath Singh is seeking re-election from Lucknow, while his colleague at the Centre Smriti Irani is again taking on Rahul Gandhi in Amethi.

Union ministers and BJP leaders Rajyawardhan Rathore (Jaipur Rural-Rajasthan), Arjun Ram Meghwal (Bikaner-Rajasthan) and Jayant Sinha (Hazaribagh-Jharkhand) are also in the fray in this phase.
