For Trudeau, there are also painful historical parallels. His father, former Prime Minister Pierre Trudeau, separated from his wife, Margaret, in 1977, when he was in office. The development is one of the biggest personal crises for Trudeau since he became prime minister in 2015, especially since he often stresses the importance of family life. The couple made the announcement a week after Trudeau unveiled a massive cabinet shuffle in a bid to boost the fortunes of his Liberal Party, which is trailing in the polls. Aides said he was determined to lead the Liberals into the next election, which must be held by October 2025.
