The independent committee tasked with investigating Hong Kong’s deadly Tai Po blaze has finished 21 sessions of evidential hearings in three rounds, pointing to multiple apparent loopholes in the supervision of the estate’s renovation project and the government’s regulation of fire hazards.

The inferno broke out on November 26 last year when all eight blocks at Wang Fuk Court were undergoing exterior maintenance work and were covered in scaffolding and mesh netting.

The fire tore through seven blocks, killing 168 people and becoming the deadliest in Hong Kong since 1948.

Chief Executive John Lee Ka-chiu ordered the creation of the committee, chaired by Justice David Lok Kai-hong, to investigate the cause of the disaster and identify any systemic problems in the lucrative building maintenance sector.

Ahead of the fourth round of hearings on Wednesday, the South China Morning Post sums up the findings so far.
