A charity overseen by Glasgow's Lord ­Provost made its biggest donation to another organisation chaired by the same public official.

The Lord Provost Goodwill Trust Fund gifted £25,000 to a body that also has civic leader Sadie Docherty as a trustee.

Tory councillor David Meikle said he was "surprised", and unclear why the decision was made.

The Goodwill Fund was set up by Glasgow City Council in 2010 thanks to a £250,000 donation from Labour peer and tycoon Willie Haughey.

It aims to tackle ill-health and address hardship.

At the time of his gift, Haughey said: "I am delighted to be involved in this new charitable fund. While I am happy to donate some of my own money, I will be contacting some of Glasgow's other well-known business people and urging them to donate as well." However, the Sunday Herald revealed in 2013 that the Haughey donation was the only financial contribution made to the charity in its first two years.

According to the charity's latest accounts, covering 2012-13, its biggest donation was to the Lord Provost's Fund for Vulnerable Citizens, which was set up in 2011.

Docherty is also a trustee of this charity and the chairwoman of both organisations.

The donation was made because the Vulnerable Citizens charity was deemed to be running low on funds.

The second-biggest published donation was £20,000 to the Clutha Appeal Fund, set up to help people affected by the helicopter tragedy.

Meikle said: "I'm surprised that the Goodwill Fund is being used in this way. The purpose of the fund is supposed to be about tackling poverty, helping vulnerable people and advancing community development. So I'm unclear why its funds are being reallocated to another Lord Provost charity."

A spokeswoman for the council said: "It is entirely appropriate to make this donation to help vulnerable people." On the guidance that grants should "usually" be limited to four-figure sums, she said: "There can be and are exceptions."
