More than 60 pages of WhatsApp messages between Democratic Unionist Party (DUP) ministers have been published by the UK Covid-19 Inquiry.

The messages give an insight into the thoughts of some of the party’s most senior figures as the pandemic spread.

In often candid exchanges, messages include jibes at ministers from other parties in Stormont’s executive.

The WhatsApp group chat covers the period between January and November 2020.

On 17 January, six days after the executive was restored following a three-year-hiatus, a person whose name has been redacted by the inquiry wrote: “SF [Sinn Féin] doesn’t seem to have matured at all!”

Emma Little Pengelly, who was then a DUP special adviser and is now deputy first minister, replied with apparent sarcasm.

“Well, why not – let English taxpayers subsidise our free prescriptions, lower rates, no water charges, lower tuition fees and free prescriptions.. but hey, how dare you guys starve us of funding #Perfidious Albion,” she wrote.

Lord Weir, who was education minister at the time, commented on 13 March about the head of the Catholic Church in Ireland writing to him to call for schools to be closed.

The DUP minister said of the Archbishop of Armagh, Eamon Martin: “Wasn’t aware of his qualifications in virology.”

A person whose name has been redacted replied: “Write back and tell him we don’t live in the South [Republic of Ireland] and that his institution hasn’t the best track record of looking out for the welfare of kids.”

On 14 March, there was criticism of Sinn Féin deputy leader Michelle O’Neill, who was deputy first minister at that time, after she broke ranks with the executive to call for school closures.

Edwin Poots, the DUP agriculture minister at the time, acknowledged that schools would have to close at some point, but said the “response needs to be measured and reassuring”.

On 17 March, as the pandemic became more acute, Mrs Little-Pengelly proposed a “four-nations press conference” with the prime minister.

“All devolved regions with PM on televised conference to reassure people,” she wrote.

Mrs Little-Pengelly said the public “need to see leaders speaking”, adding that “any confusion compounds panic”.

Some messages point towards tensions between executive ministers during meetings to discuss the pandemic.

There were several jibes at Justice Minister Naomi Long, leader of the Alliance Party.

On 7 May, Lord Weir said Mrs Long was “hard to listen to”, and on 23 July he wrote: “Naomi talking about wind instruments – oh the irony!”

On 9 November, Lord Weir said Ms O’Neill, was “making a pig’s ear of this” to which Mr Poots replied: “Comes naturally.”

On 6 August, Lord Weir referred to an exchange between Mr Poots and Nichola Mallon, at the time the Social Democratic and Labour Party’s minister in the executive.

He wrote: “Edwin you managed to take her from zero to skywards v v quickly!!”

Mr Poots replied: “It’s a speciality of mine. Enjoying the sour bake on her face now.”

In another message on 15 June which appears to reference Sinn Féin Junior Minister Declan Kearney, Lord Weir wrote: “Where would we be without Declan’s philosophical musings.”

A person whose name is redacted replied: “At a shorter meeting.”
