She rallied her party by slamming “the anti-growth coalition” as the enemies of progress in Britain, holding back infrastructure and enterprise across the country. 

Now, former prime minister and Norfolk MP Liz Truss is objecting to a major waste incinerator project being built just outside her constituency. 

In a letter to the Planning Inspectorate, Ms Truss said the proposed facility in Wisbech, Cambridgeshire, would have “adverse consequences” for her South West Norfolk constituents.

The £300m project, known as the Medworth Incinerator, promises to generate partly-renewable electricity and usable heat from non-recyclable waste, that would otherwise go to landfill.

During her time as prime minister, which ended in October after just 49 days in office, Ms Truss had stressed the need for Britain to develop new sources of energy production and become less reliant on Russia. 

But Ms Truss said the company behind this scheme - MVV Environment Ltd - had failed to consult her constituents, neglecting their “serious concerns” about its “totally unsuitable” location.

She wrote: “Reports from the company released during the consultation also omitted vital information, including parts related to location monitoring.

“This is not the extensive and thorough consultation you would expect from a Nationally Significant Infrastructure Project.

“The site chosen is totally unsuitable when you analyse the surrounding infrastructure.

“The A47 requires major improvement, irrespective of the proposals.

“Traffic is always heavy around the A47/A1101 Elme Hall roundabout and its tributary network. 

“To encourage heavier and more extensive traffic flows, with around 300 HGV movements expected per day, would not only add to congestion but totally immobilise the area as people try to get to work and take their children to school."

She added that the traffic would disrupt businesses and worsen local air quality. 

MVV has said it “will carefully look at local road networks and available waste in the area in order to develop a transport plan that will minimise impact on the existing infrastructure”.

The Planning Inspectorate is currently collating all of the letters it has received regarding the project and will hold a meeting to discuss issues raised in the new year. 

A final decision on the project will eventually be made by Grant Shapps, the secretary of state for business, energy and industrial strategy.
