The article, published in March, alleged that the firms “were behind a probe and ‘witch hunt’ into killings by British Troops during the Irish troubles and were secretly receiving millions of pounds in Legal Aid”.

However, the newspaper admitted: “We acknowledge that these allegations were wrong and we had not intended to impugn the professional integrity or impartiality of either firm who act for clients on all sides of the political and religious divide.

“We apologise for any unintended suggestion to the contrary.”

Belfast lawyer Paul Tweed, who acted for KRW Law, said the firm is “very satisfied with the vindication of the firm by the retraction and apology”.

In a statement, senior partner Kevin Winters reiterated his determination to protect the firm’s reputation, and to continue to represent individuals, regardless of their political or religious beliefs, without fear or favour.
