Dagenham and Rainham.

Mullane's most significant recent action was breaking with Labour five times on welfare reform. On 1 July and again on 9 July 2025 she voted against the Universal Credit and Personal Independence Payment Bill at both second reading and third reading, and backed rebel amendments protecting disabled people with fluctuating conditions and uprating LCWRA payments in line with inflation. The data underlines the pattern starkly: she votes for disability benefits protection 100% of the time against a party average of 12%, and sits 50 percentage points below her party on welfare reform backing. On this issue she is one of Labour's most consistent dissenters.

Otherwise she is a broadly loyal MP -- voting with Labour 95.7% of the time overall -- with an 89% participation rate, above the Commons average. Her stance profile shows strong alignment with workers' rights (90%) and progressive taxation (97%), but low scores on parliamentary scrutiny (4%) and Lords scrutiny (0%), suggesting she follows the government line on procedural matters. Her 25 speeches have concentrated on crime, immigration, social care, and the economy; she also speaks regularly on local government and fiscal policy. Her seat on the Home Affairs Committee aligns with that crime and immigration focus.

Locally, coverage over the past 90 days has been dominated by crime and housing stories, though the highest-impact pieces were positive: she secured road resurfacing on Rainham Road North, coordinated a multi-agency response to a rat infestation, and has campaigned for step-free access at Dagenham East station. These suggest an MP who combines active constituency casework with a clear parliamentary priority -- protecting disability and welfare entitlements -- even at the cost of party loyalty.
