London, June 7 (IANS): With less than 24 hours to go before voting begins in Britain's general election, leaders of the two main parties on Wednesday hit the streets across the nation for a final day of campaigning.

Conservative Party leader Theresa May, who seeks to retain her job as Prime Minister in Thursday's vote, began her day with a visit to a Smithfield meat market in London before heading to central and eastern England.

Her rival, Jeremy Corbyn of the Labour party travelled north to Glasgow before making his way back south to London, passing through several towns and cities in England and Wales on the way, Efe news reported.

Corbyn said that public services, particularly the National Health Service, would be safer in his hands.

Home security and police numbers have been at the crux of the campaign in the light of last week's terror incident in which seven people were killed when three militants mowed down pedestrians on London Bridge and launched a stabbing rampage at a nearby market.

The current head of government and former Home Secretary on Tuesday said she would alter current human rights laws if it was deemed necessary in order to crack down on terrorism in London.

Meanwhile, Corbyn criticised cuts to police numbers that were made when May was the government minister responsible for Britain's Home Office.

Around 50 million Britons are eligible to vote in the general election on Thursday.

At the onset of campaigning a month ago, May led Corbyn in the public opinion polls with an average of around 20 points. But according to a new polling data, the rivals were neck and neck now.
