Business groups and MPs have expressed frustration over suggestions that plans to upgrade rail links in the Midlands and the North are to be watered down.

The PA news agency understands Transport Secretary Grant Shapps could announce the results of the integrated rail plan - which should include an announcement on HS2 between Birmingham and Leeds - this Thursday.

There is growing speculation the Government will commit to building the western leg of HS2 from Birmingham to Manchester but put the brakes on the Leeds option following years of spiralling costs.

The Sunday Times has suggested the rail plan will also contain high speed upgrades across the North and the Midlands, cutting journey times from Leeds to Sheffield, Crewe to Manchester and from Birmingham to East Midlands Parkway, near East Midlands Airport on the Nottinghamshire/Leicestershire border.

Previous reports have suggested the eastern leg could even end at East Midlands Parkway, linking it to the Midlands Mainline.

Henrietta Brealey, chief executive of Greater Birmingham Chambers of Commerce, said: 鈥淚t鈥檚 disappointing to see speculation mounting again about the long-term future of the eastern leg of HS2.

鈥淗ere in Greater Birmingham, we鈥檝e seen first hand the positive impact it has had on creating jobs, attracting wider private sector investment and raising the profile of the region on the global scale.

鈥淚f the Government is serious about delivering the levelling up agenda, then it is essential that HS2 is delivered in full 鈥 as the PM himself committed to at the start of his premiership.

鈥淚n the meantime, we will await to review the publication of the Integrated Rail Plan and hopefully we will see a commitment to proceeding with the Midlands Rail Hub 鈥 a project which has gathered significant local support from businesses and stakeholders alike.鈥

The i said the plan in the North will only commit to investing into existing Transpennine route upgrade proposals rather than build a new high-speed route via Bradford, which would also create increased capacity.

Naz Shah, Labour MP for Bradford West, said: 鈥淭his is Boris pulling the whole damn rug from under our feet and ripping up the floor behind him!鈥

Shadow transport secretary Jim McMahon said ministers were attempting to 鈥渜uietly back out鈥 of infrastructure schemes that they had 鈥渃ommitted to dozens of times鈥.

Deputy Labour leader Angela Rayner said Northern Powerhouse Rail 鈥 the name given to proposals for an east-to-west high-speed train line across the North 鈥 had been 鈥渁 fraud鈥.

The speculation comes despite Prime Minister Boris Johnson pledging his 鈥渃ommitment to Northern Powerhouse Rail鈥 shortly after entering Downing Street in 2019.

As recently as the Conservative Party conference in Manchester last month, Mr Johnson said in his leader鈥檚 speech that the Government 鈥渨ill do Northern Powerhouse Rail, we will link up the cities of the Midlands and the North鈥.

Conservative MP Kevin Hollinrake, who represents Thirsk and Malton in North Yorkshire, told the i the trimmed back plans indicated the Government was 鈥渘ot willing to put our money where our mouth is鈥.

Mr McMahon said: 鈥淚t鈥檚 laughable that the Government expects people in the North to be grateful for some half-baked and repackaged plans, as they attempt to quietly back out of promises made on the vital major infrastructure projects those communities need so badly.

鈥淔ailure to deliver on HS2 and Northern Powerhouse Rail 鈥 schemes ministers have committed to dozens of times 鈥 is not only insulting, it is actively holding back investment and opportunity that could benefit millions of people.鈥

A Department for Transport spokeswoman said: 鈥淲ork is continuing on the integrated rail plan.

鈥淲e will publish it shortly and do not comment on speculation.鈥
