The government is facing calls to carry out an urgent investigation after reports emerged that a phone belonging to Liz Truss was hacked by Russia.
The Liberal Democrats and the Labour Party have described the allegations as “extremely serious” and “concerning”.
Agents suspected of working for Russian President Vladimir Putin allegedly hacked the former prime minister’s personal phone during the summer Tory leadership campaign, gaining access to details of negotiations with key international allies.
Private messages between the then foreign secretary and cabinet minister Kwasi Kwarteng were also accessed, according to the Mail on Sunday.
These details were reportedly suppressed by Boris Johnson, who was prime minister at the time, and Cabinet Secretary Simon Case.
The government hasn’t confirmed the reports and Sky News hasn’t been able to independently verify the claims.
Speaking to Sky News, chair of the Defence Select Committee Tobias Ellwood said he was not aware of the incident but had seen the reports.

“This is a constant threat from Russia, they are getting better and better at these cyber attacks and hacking. We take the most stringent measures to make sure it doesn’t happen,” he told Sky News.
“It is something for the intelligence and security committee to investigate further.”

‘Serious questions’ need to be answered
In response to the report, shadow home secretary Yvette Cooper said it shows the “severity of the threats” from countries that want to harm the UK.
“There are immensely important national security issues raised by an attack like this by a hostile state, which will have been taken extremely seriously by our intelligence and security agencies,” she said.
“There are also serious security questions around why and how this information has been leaked or released right now, which must also be urgently investigated.”
“If it turns out this information was withheld from the public to protect Liz Truss’s leadership bid, that would be unforgivable.
“We cannot allow the Conservative Party’s political games to be put ahead of the country’s interests and national security,” she added.
A government spokesperson said there are “robust systems” in place to protect against cyber threats, including regular security briefings for ministers and advice on how they can protect their personal data.
But, they added: “We do not comment on individuals’ security arrangements.”
Speaking to reporters in front of his residence at Rideau Cottage, in the country’s capital, Ottawa, he said “internal battles” mean that he “cannot be the best option” in the next election.
“I don’t easily back down faced with a fight, especially a very important one for our party and the country. But I do this job because the interests of Canadians and the well-being of democracy is something that I hold dear.
“A new prime minister and leader of the Liberal Party will carry its values and ideals into that next election. I am excited to see that process unfold in the months ahead.”
Former governor of the Bank of England, Mark Carney, is among the favourites to succeed him.
Chrystia Freeland, whose stunning resignation as finance minister and deputy prime minister precipitated the current crisis, leads in the polls.
Other front-runners are the former premier of British Columbia, Christy Clark, current finance minister Dominic LeBlanc and minister of foreign affairs, Melanie Joly.
Mr Trudeau, who has been prime minister since 2015, faced calls to quit from a chorus of his MPs amid poor showings in opinion polls.
He came under further pressure after Ms Freeland quit in December because of policy disagreements, including over how to handle possible US tariffs imposed by Donald Trump‘s incoming administration.
Mr Trudeau’s resignation comes as the polls show his party is likely to suffer a heavy defeat to the official opposition Conservatives in an election that must be held by late October.
The Liberals must now name an interim leader to take over as prime minister ahead of a special leadership convention.
Mr Trudeau came to power 10 years ago following a decade of Conservative Party rule and was initially praised for returning the country to its liberal past.
But he has become deeply unpopular with voters in recent years over a range of issues, including the soaring cost of food and housing and surging immigration.
He is the eldest son of Pierre Trudeau, one of Canada’s most famous prime ministers, who led the country from 1968 to 1979 and from 1980 to 1984.
The political upheaval comes at a difficult moment for Canada internationally.
US President-elect Donald Trump has threatened to impose 25% tariffs on all Canadian goods if Ottawa does not stem what Mr Trump calls a flow of migrants and drugs into the US.
Many fewer of each cross into the US from Canada than from Mexico, which Mr Trump has also threatened.

Few one-time golden boys manage to retain their lustre long into political office.
Barack Obama just about held on to his, leaving the US presidency with his approval rating high despite his party’s 2016 loss to Donald Trump.
But Emmanuel Macron is faltering in France and Justin Trudeau steps down as head of Canada’sliberal party with his popularity in shreds. So much for Western liberal values.
In the high tides of inflation and immigration, those who were their supposed flag-bearers are no longer what electorates want.
For Mr Trudeau, it is a dramatic reckoning. His approval ratings have dropped from 65% at their highest in September 2016 to 22% now, according to the “Trudeau Tracker” from Canada’s non-profit Angus Reid Institute.
The sudden departure of his finance minister and key political ally Chrystia Freeland last month dealt his leadership a body blow, just as Canada readies itself for a potential trade war with the US which, she argued in a bracing resignation letter, his government was not taking seriously enough.

“Parliament has been paralysed for months,” Trudeau says
The man Mr Trump recently trolled as “Governor of the ‘Great State of Canada’ or ’51st (US) state'”, Mr Trudeau was as close to Canadian political royalty as it gets.
The son of the country’s 15th prime minister, Pierre Trudeau, he was famously toasted by US president Richard Nixon as “the future prime minister of Canada” when he joined his father on a state visit as a toddler.
Aged five, he met the late Queen for the first time. “Thank you for making me feel so old”, she remarked drily at a re-meet in Malta almost 40 years later.
He has led Canada’s liberal party since 2013 and served as the country’s 23rd prime minister for almost a decade.
Mr Trudeau won a resounding electoral victory in 2015 and secured the premiership through two subsequent elections, though as head of a minority government.
He made significant inroads against poverty in Canada, worked hard on nation to nation reconciliation with Canada’s indigenous communities, secured an effective trade deal with the US and Mexico in 2016 and managed to keep the public mostly on-side through the COVID-19 pandemic.
But he was a polarising figure. Holidays in exotic climes like a trip to the Bahamas in 2016 to an island belonging to the Aga Khan made him seem elitist and out of touch.
There was embarrassment when blackface images surfaced from his early years as a teacher, for which he apologised profusely.
His supposed liberal credentials smacked of double standards when he invoked emergency powers to crush truckers’ protests in 2022.
But it was the economic aftermath of the pandemic, with Canada suffering an acute housing shortage, immigration leaping under his premiership and the cost of living hitting households across the board which really piled on the pressure.
In those, Canada is not unique. But the opposition conservatives and the public at large clearly want change, and Mr Trudeau has responded.
He has announced his intention to resign as party leader and prime minister after the Liberals selects their next leader.
Mr Trudeau’s legacy may shine brighter with a little hindsight. But now is not that moment.
The question is whether his conservative opposition will fare any better in an increasingly combative geopolitical environment if, as seems likely, a candidate of their choosing wins a federal election due at some point this year.
