Former British prime minister Tony Blair has officially entered electoral campaign by voicing his “100% support” for current Labour leader Ed Miliband just one month ahead of the general elections.

Blair supported Ed Miliband’s ability to lead the country and praised him for "real leadership" on Britain's EU membership.

Some critics believe that Blair’s support will backfire and ruin Miliband’s chances to enter Number 10, calling it "Kiss of Death" for the Labour party leader.

Political commentator Hafsa Kara Mustapha told Press TV that Blair’s support will weaken Miliband.

“I think “Kiss of Death” is the perfect description of what Tony Blair has done and he has already pledged his support for Miliband in the past. So, I think you can see that it was a strategy really designed to weaken Ed. Miliband,” she told Press TV on Tuesday.

“Tony Blair remains as one of the most unpopular prime ministers in the recent history and totally even more so since he left the office, primarily because he has proved himself to be a rather money-grabbing greedy politician whose all policies are really designed to improve his personal image and his personal finances. So despite his unpopularity as an acting prime minister which is quite common so we know, prime ministers towards the ends of their terms to be more unpopular, in this case he has become even more unpopular with history,” she added.

Tony Blair faces war crime charges over the 2003 US-led invasion of Iraq.

Speaking at an event in his former constituency, Blair slammed Prime Minister David Cameron's handling of the country and warned that his pledge to hold a referendum on Britain's EU membership would cause economic "chaos"

UK political parties are intensifying electoral campaigns just a month ahead of May 7 general elections.

Britons will go to the polls on May 7 in the most unpredictable general elections for decades.
