Chennai: Polling progressed at a brisk pace in the R K Nagar assembly constituency here, with an estimated 46 per cent of the electorate casting their votes by 3 PM in the prestigious by-election

Election authorities said 46.6 per cent of the 2me3,28,234 voters in the constituency exercised their franchise by 3 PM and there were no reports of any untoward incident so far

A few issues related to Electronic Voting Machines (EVMs) were imdiately sorted out and polling was “brisk”, they said

The by-election is being held to fill the vacancy caused by the death of sitting MLA and All India Anna Dravida Munnetra Kazhagam (AIADMK) supremo J Jayalalithaa in December last year

Earlier, polling began at 8 AM, with people arriving to exercise their franchise across booths in the constituency in North Chennai, braving the misty conditions

R K Nagar, represented twice by Jayalalithaa, has an electorate strength of 2,28,234 — comprising 1,10,903 men, 1,17,232 women and 99 transgenders

The key contenders in the poll are ruling AIADMK’s E Madhusudhanan, main opposition Dravida Munnetra Kazhagam (DMK) candidate N Maruthu Ganesh and sidelined AIADMK leader T T V Dhinakaran, contesting as an Independent

The bypoll is being seen as an acid test for the AIADMK, as it is the first election since the death of Jayalalithaa and after it got the ‘Two Leaves’ election symbol back following the merger of the factions led by Chief Minister K Palaniswami and his present deputy and former rebel O Panneerselvem

Jailed leader V K Sasikala-Dhinakaran camp lost the symbol case before the Election Commission which last month held that the EPS and OPS group commanded majority in the party’s organisational and legislature wings

Though as many as 59 candidates are in the fray including from the BJP, it is mainly seen as a fight between the AIADMK, its rival faction led by Dhinakaran and DMK

Madhusudanan is a party veteran who hails from the constituency. Ganesh too hails from the area

Elaborate security arrangements are in place with about 2,000 state police personnel, 15 companies of Central Armed Police Forces, including CRPF, deployed across 256 polling stations

The polling process is being monitored by nine observers, considered the highest for a single assembly constituency

This includes general, special, police and expenditure officials.
