Since writing the letter, Mr Percy has reportedly received a further £20,000 from Aquind through his local party, and through his constituency association another £6,000 in 2019.
It is also claimed that in 2014, Mr Percy received a donation of £10,000 to his constituency party from another company, Offshore Newcastle Group, which at the time Mr Temerko, who was born in Ukraine and became a British citizen in 2011, was a director.
Mr Percy told the JC: “Just because somebody donates to a political party doesn't mean that they aren't then allowed to lobby MPs or the government on an issue.
“If we applied that rule then Labour MPs would never be able to advocate on an issue given how much they are personally sponsored by Trade Unions who often fund their campaigns too.
“My only interest in an issue is whether or not a proposal, policy or scheme makes sense and is in the interests or my constituents and the UK.”
Mr Percy said that he “businesses regularly petition me about the UK's high energy costs so of course I have advocated for new forms of supply and generation in the UK to lower those costs, support UK jobs and to green our grid”.
He added that that explained why he had “met with and supported” those behind a variety of green energy projects, “the same goes for an interconnect of which there are a number of projects”.
All donations made by Mr Temerko and Aquind were lawfully and properly declared.
