Tony Blair said he feels motivated to return to frontline politics and refused to rule out standing again as a Labour MP.
The former Prime Minister warned Theresa May is not being reasonable when it comes to the UK’s departure from the European Union.
Mr Blair said he “almost feels motivated to go right back into it” as a politician, as he said Britain is being “hijacked” by Brexit backers.
He argued the issue is “bigger than party allegiance” at the June 8 vote, adding voters should find out where candidates stand on it.
The ex-Labour leader told BBC Radio 4’s The World This Weekend: “I feel for the first time since I first came into politics, I look at the British political scene at the moment and I actually almost feel motivated to go right back into it.
“I just feel we’re allowing ourselves to be hijacked by what is actually quite a small group of people with a very strong ideology.
“Someone like Theresa May, you look at her and she’s very sensible, very solid, she’s a perfectly decent person, I agree with a lot of what she says – what she says about energy costs today, most people would say ‘fair enough’.
“But on this issue, which is the biggest issue of our time and which will have a dramatic impact on our future, on our economy, on our living standards and on the younger people of this country, on this issue she’s not reasonable.”
Told jokingly that Labour may still be in search for candidates for the forthcoming election, Mr Blair replied: “Well, I tell you what I fancy, I fancy doing whatever I can to at least make this debate in the election into a proper debate.
“We can read the polls… I’ve never known polls like this.”
When asked who would be best-suited to become Prime Minister, Mr Blair refused to back Jeremy Corbyn, of whom he has been a vocal critic in the past.
He said: “I’m basing my statements about the campaign really on that if the polls are right – I’m not saying they should be right, I’m not saying they are right, I’m just saying if they’re right – frankly that is not the dominant question in this campaign.
“The dominant question is what’s the mandate that Theresa May is going to claim on June 8.”
