Harpenden and Berkhamsted.

Collins has been most visible locally, intervening repeatedly in a planning and enforcement crisis at Flamstead, where she liaised with Dacorum Borough Council, wrote formally to government, and helped push for an emergency injunction after an unauthorised encampment caused significant distress to residents. Her rebel votes tell a second story: in June 2025 she backed two amendments to the Terminally Ill Adults (End of Life) Bill against her party's majority, placing her among the more pro-access wing of the Lib Dems on assisted dying -- a 12-percentage-point gap from her party's average on that stance.

A 99.4% party-line voter overall, Collins departs from the Lib Dem mainstream mainly on that issue and on local democracy, where she votes in favour 10 percentage points more than the party average. Her participation rate of 70% sits below the Commons norm. She has backed Lords scrutiny of government legislation on 96% of relevant votes, consistently opposing the government's attempts to overturn Lords amendments to the English Devolution and Community Empowerment Bill. Her 253 contributions span economy, technology, local government, social care, and health -- a broad range without a single dominant specialism, though no committee role currently focuses her activity.

Her constituency news coverage over the past 90 days has been dominated by the Flamstead encampment dispute, where she earned visible credit for constituent responsiveness, though the underlying planning enforcement situation took time to resolve. Across 81 articles, her average media score is marginally positive at 0.06 -- reflecting routine coverage rather than any sustained controversy. She holds no select committee seat, so her influence runs mainly through chamber speeches and constituency casework.
