Michael Heseltine, thea former Tory deputy prime minister and remain campaigner, intensified that warning on Sunday night, as he urged voters to judge the leave campaign by their “friends” Donald Trump and Vladimir Putin.
“They are playing with fire. We have been here before. The same themes echoed through the 1920s and 1930s. Every time I hear those who proclaim the desirability of independence and national sovereignty, I shudder with the memory of 1940,” he said.
“We were sovereign. We were alone. Our convoys sank in the Atlantic. Our finances bled. Our overseas armies faced isolation. That was real sovereignty and we were powerless until America entered the war. Peace was hard won. Europe came together to ensure it must never happen again.
“Every world friend we have knows this, warns us of the danger of forgetting it, begs us to maintain our leadership in preserving the framework of stability.”
