Royal Mail chairman Peter Long is stepping down just months after shareholders revolted over the new chief executive’s bumper pay packet.

The group said Mr Long was leaving the company after realising it was “no longer possible” to continue as non-executive chairman of Royal Mail, while also serving as executive chairman of estate agency chain Countrywide.

He will step down immediately and be replaced by Royal Mail board member and former Axa Sun Life boss Les Owen.

“Peter has reviewed his board appointments and concluded it is no longer possible for him to remain executive chairman of Countrywide and non-executive chairman of Royal Mail,” the company said in a market announcement.

Mr Owen joined the Royal Mail board in 2010, becoming a member of its audit and risk committee and remuneration committee, and chairing its pensions committee during a major review of its pensions scheme.

He previously served as chief executive of AXA Sun Life and AXA Asia Pacific Holdings.

Mr Long, who has been chairman at Royal Mail since September 2015, said: “It is with a heavy heart that I step down from the Royal Mail board.

“Over my three years as chairman, I have taken great pride in what has been achieved by the group.

“It is a company with an incredible heritage. Operating in a challenging environment, it is positioning itself well for diversified growth under the leadership of Rico Back and his executive team.”

The changeover comes just months after the board was left with a bloody nose following a row over a salary rise for its new Zurich-based chief executive Mr Back.

The directors’ remuneration report was rejected in a vote at its annual general meeting in July, with 70% of proxy shareholders voting against the package.

While the vote was non-binding, the board said it would consult further as continued to review its remuneration policy.

Investor advisory firms ISS and Glass Lewis had suggested shareholders vote against the remuneration report, in part because Mr Back was set to receive a higher salary than outgoing boss Moya Greene.

Mr Back is being paid a £640,000 annual salary, £100,000 more than his predecessor.

But Royal Mail insisted that differences in pension arrangements meant his “fixed pay” will be “exactly the same” as Ms Greene’s.

Mr Back has decided to stay in Zurich, Switzerland, with plans to commute regularly to work at Royal Mail’s London headquarters.

Royal Mail also made headlines for paying a near-£6 million “golden hello” to Mr Back, when he joined from General Logistics Systems (GLS) – Royal Mail’s European parcels business – earlier this year.
