The Home Secretary caused a legal storm with an “ill-advised” tweet about the deaths of 39 migrants while the people-smuggling trial was going on.

On October 23, the anniversary of the tragedy, Priti Patel’s Twitter account posted: “One year ago today, 39 people lost their lives in horrific circumstances at the hands of ruthless criminals.

“My thoughts remain with everyone who was affected by that day, particularly the loved ones of the people who so tragically died.”

The comments were made as the prosecution of four alleged people-smugglers linked to the deaths was continuing at the Old Bailey.

I don't know whether the court can invite the Government to delete that tweet?

Commenting on the post, one man wrote: “Dear Home Secretary. There is an active criminal trial ongoing.

“Your comments are ill advised and in case you are not au fait with such things, in contempt of court.”

The post was retweeted and liked more than 300 times before it came to the attention of a defence lawyer and the trial was halted.

In the absence of the jury, Alisdair Williamson QC complained about the description of “ruthless criminals”, especially as she was a senior Government minister.

He said: “It is unhelpful to say the least and a lot worse could be said.

“l don’t know what course could be taken. I know I don’t tweet personally. If action could be taken before the jury gets home.

“I don’t know whether the court can invite the Government to delete that tweet?”

Prosecutor Bill Emlyn Jones said: “Contact was made with the Home Secretary’s office but I have not been updated on any response.”

It’s a fundamental principle of our criminal justice system that those on trial are presumed to be innocent until proven to be guilty and it is you and you alone who are going to decide whether they are guilty or not guilty

Before he sent jurors home for the weekend, Mr Justice Sweeney warned them to ignore comments on social media from politicians.

He said: “It is a year today since the bodies of the victims were found.

“No doubt the anniversary will be commented on whether in mainstream media or social media.

“And whether by politicians, likewise journalists or others, inevitably there is a risk that such comments may assert or imply guilt of amongst others the men who are in your charge, two of whom are charged with the manslaughter of the victims.

“You must ignore any such comments.

“It’s a fundamental principle of our criminal justice system that those on trial are presumed to be innocent until proven to be guilty and it is you and you alone who are going to decide whether they are guilty or not guilty.”

The tweet was live for more than an hour before it was deleted.

Later, the lawyer and author known as the Secret Barrister tweeted: “I suggest that @pritipatel start following @attorneygeneral.

“Might save future embarrassment/imprisonment.”

The incident came amid growing tension between Government and the legal profession.

The Home Secretary and Prime Minister Boris Johnson had faced repeated calls to apologise for “hostile” comments about the profession.

On the same day as Ms Patel’s tweet, Mr Justice Sweeney had also presided over a preliminary hearing for a man charged with a terrorist plot to kill a solicitor over his role in representing immigrants.

Following the guilty verdicts, Ms Patel said: “Today’s convictions only strengthen my resolve to do all I can to go after the people smugglers who prey on the vulnerable and trade in human misery.

“I’m determined to bring callous people smugglers to justice and keep our communities safe from the actions of horrendous organised crime groups.”

A Home Office spokesperson said: “The Home Secretary’s tweet intended to refer to individuals who were involved in the incident and had already entered guilty pleas. The tweet was not intended to reference individuals involved in the ongoing trial.

“However, as soon as concerns were raised, the tweet was deleted.”
