The former chief executive of RSA’s Irish operations will today bring a constructive dismissal case to the Employment Appeals Tribunal.

Philip Smith, who left the company in 2013, claims he was the "fall guy" for problems at the British insurer's Irish branch.

The Central Bank continues to investigate financial irregularities at the firm dating from 2013, and may levy a fine of up to €5m, the Irish Times reports. It will publish its findings later in the year.

Smith was suspended on November 8 of that year, pending the outcome of an investigation into issues in claims and finance functions discovered in a routine audit. On November 28, RSA revealed Smith had resigned and received no severance pay.

RSA, which has poured millions into its subsidiary to maintain a solvency ratio greater than 200 per cent, has said it will the fight Smith's case “tooth and nail.”

The tribunal has set aside five days for the hearing.
