James Wharton, Baron Wharton of Yarm

Wharton was appointed Parliamentary Under-Secretary of State for Communities and Local Government (Minister for Local Growth and the Northern Powerhouse), the first minister dedicated to the government proposal.[8] However, he rarely left London — a fact that was only released after a judge ruled the department had to comply with a freedom of information request — a process which took 26 months.[9] After Theresa May's appointment as Prime Minister in July 2016, Wharton was appointed Parliamentary Under-Secretary of State at the Department for International Development.

On 16 May 2013, Wharton came top of a ballot of backbench MPs which entitled him to introduce a Private Member's Bill during the 2013–14 parliamentary session. He chose to address the issue of a referendum on Britain's membership of the European Union by attempting to enshrine the Conservative Party Position into law, by introducing the European Union (Referendum) Bill 2013-14. He faced criticism from opposition MPs for taking on the EU Referendum Bill as his Private Members Bill, and it was suggested by them that the move may have been more advantageous to his political career than of direct benefit to his constituents.[10] Wharton himself had previously suggested that too much time was spent debating the issue of Europe, but has since argued that his Private Member's Bill was designed to put the issue to rest.[11]

After the Bill did not pass the House of Lords, Wharton blamed Labour and Liberal Democrat obstructionism.

After being elected MP for Stockton South, Wharton made stated his opposition to a development occurring in Preston Park. The plans, backed by Wharton's predecessor Dari Taylor, included relocating Egglescliffe School to the park. Wharton accused Stockton Borough Council of refusing to listen to the "democratic will of local people."[12]

After a developer withdrew its £750,000 investment to regenerate Thornaby Town Hall, Wharton called for the building to be given to the Town Council. Originally the building belonged to Thornaby-on-Tees Borough Council; however, due to local government reorganisations, it was taken on by Stockton Borough Council in 1974. In 2012 the Town Council purchased the building from the borough council with the hope of enabling the building and the surrounding area to be restored.[13]

In 2014, Wharton denied allegations by a UKIP councillor that a letter he wrote to constituents on the subject of the conflict in Gaza had "been sent to those residents who may reasonably be expected to be Muslims, based only on their names".[14]

Wharton has made a number of visits to Sri Lanka, including as a delegate of the Commonwealth Parliamentary Association, with the charity International Alert and as a guest of the Sri Lankan Government, including four visits in nine months during 2012. Wharton denied allegations that he had become too close to the Sri Lankan government, saying that he had made friends on both sides of the ethnic divide and that the lack of a Sri Lankan community in his constituency helped him be "objective"[15]

In 2010, Wharton assisted Conservative Town Councillor Jason Hadlow's company Trocabart to secure £30,000 in aid from the former Regional Development Agency, One North East; the business failed and had been closed. He claimed that his only motivation was to promote the growth of jobs in the Teesside area. There has been no evidence of any financial connection between Wharton and the firm.[16]

Wharton was accused of a breach of Parliamentary protocol, by attending a neighbouring constituency to take part in a photo call at the new Hitachi factory in Phil Wilson's Sedgefield constituency, without advising Wilson in advance. Wharton acknowledged that he had driven minister Brandon Lewis to the site and been photographed there, but said that he had not been there for the duration of the visit.[17] Speaker John Bercow said that MPs should observe the spirit of the rules.[18]

In 2019, Wharton took on the role of Campaign Manager for Boris Johnson in his successful bid to replace Theresa May as leader of the Conservative Party.[19]

In Boris Johnson's 2020 Dissolution Honours List, James was selected for a peerage.[20] He was created Baron Wharton of Yarm, of Yarm in the County of North Yorkshire', despite the town of Yarm being in the borough of Stockton-on-Tees, in the morning of 2 September 2020.[21][22] Lord Wharton was introduced to the House of Lords on 10 September 2020, becoming the youngest male member of the House at the age of 36.

In 2021, Wharton was appointed chair of the Office for Students, an appointment endorsed by the Education Select Committee.[23] Kate Green, the Shadow Secretary of State for Education, criticised the appointed for alleged cronyism.[23] After it emerged that Wharton was chosen over Ivor Crewe, who was also interviewed, Wharton's lack of experience in higher education was unfavourably compared with that of Crewe.[24][25] On a potential conflict of interest, as the independent regulator while retaining the Conservative whip as a peer, Wharton said he spoke to party whips and said "they would give me more latitude and understand that I may need to vote against or speak against some of the things the party in government could bring forward".[23]

In May 2022, Wharton addressed the Conservative Political Action Conference (Cpac) Hungary in Budapest. Wharton's attendance drew widespread criticism as the event was attended by a number of people who have previously expressed antisemitic and racist views. Wharton's video message was delivered on the same day as Zsolt Bayer, a Hungarian television talkshow host who has been accused of racism, took to the stage. Bayer has previously called Jews “stinking excrement” and referred to Roma as “animals”.

Anneliese Dodds, the shadow women and equalities secretary and chair of the Labour party, called on the Conservative Party to "condemn Lord Wharton for sharing a platform with racists, antisemites and rightwing extremists".[26]

Following Wharton's attendance at Cpac, the University and College Union called for Wharton’s resignation and the Union of Jewish Students voiced concern.[27]
