The Most Influential Leftist You’ve Never Heard Of
British politics is in turmoil. The two party system has collapsed, the far right has won huge gains across the country. Crises of this scale can create huge opportunities for socialists too, but only when the left is organised and ready.
Peter Mertens is the general secretary of the Workers’ Party of Belgium. If recent years in British politics have had a manic-depressive quality, with extreme highs and extreme lows, the Workers’ Party of Belgium under Mertens takes a very different approach. They might be relatively unknown in the UK, but as we speak, they’re fourth in the national polls, and leading in Brussels. They’ve got 15 parliamentary seats – not bad for out and proud Marxist-Leninists.
How have they done it? By growing cautiously and deliberately. They run community health clinics, organise locally, and impose strict internal discipline. Their party prioritises unity and strategy. But how well-placed is it to take on the overlapping crises of the 21st Century? What advice does Mertens have for Zack Polanski? How can we stop middle class people taking over and dominating the left? And how is politics like football?
