Fourth wife goes free: Hilarious South African airline ad campaign pokes fun at polygamist president Jacob Zuma's sixth marriage

A quirky South African airline have poked fun at their own polygamous president - by advertising a tongue-in-cheek promotional flight where 'your fourth wife goes free'.

Kulula Airlines are offering refunded flights for any customer who happens to have a fourth wife, just like the country's polygamous leader Jacob Zuma.

Zuma, 70, married his fourth current wife, in what was his sixth marriage, when he tied the knot with Gloria 'Bongi' Ngema at the weekend.

Cheeky: Kulula Airlines released their tongue-in-cheek advert to coincide with president Jacob Zuma's fourth current marriage

And quick to cash in on the well-known polygamist lifestyle of their president, the cheeky airline unveiled the offer 'inspired by regular VIP travelers with sizeable spousal entourages'.

Kulula's offer, which runs from April 23 to April 30, states: '... not only will you get a great deal on kulula.com flights for your first three wives, but your fourth wife will fly free, mahala, on the house.'

The airline's Facebook page goes into more detail about the offer, adding: 'Inspired by regular VIP travelers with sizeable spousal entourages, the offer is open to all fourth wives when the family travels together on the Jo’burg to Cape Town route.'

Four weddings: South African president Jacob Zuma and his new wife Bongi Ngema - one of his four current spouses - cut a cake as they take part in a traditional ceremony known as Umgcagco at his home in Nkandla

The offer also states it only applies if a family have already bought a ticket from them for the husband and all wives.

Customers have to present evidence of the marriages, at which point they say the fourth wife's marriage will be refunded.

Mr Zuma's latest nuptials follow a prolonged engagement to Ms Ngema, a devoutly religious business graduate who has worked for companies including IBM and Deloitte & Touche and has often been seen at her new husband's side.

The couple's marriage means she will now officially join the presidential household in his home village of Nkandla, where she will live alongside the statesman's three other wives.

Mr Zuma, a former goatherd who spent a decade in prison under the apartheid regime, wed his long-standing first wife Sizakele Khumalo, 69, in 1973.

He married Nompumelelo Ntuli, 37, in 2008 and wed third current wife Thobeka Madiba, 39, in 2010.

The six-times married statesman has also had two aborted unions.

He divorced South African cabinet minister Nkosazana Dlamini-Zuma in 1999 and another wife, Kate Mantasho-Zuma, committed suicide in 2000. The president's then trio of wives were all at his side as he was inaugurated in May 2009.

All four will now be treated as first ladies and will share Mr Zuma's spousal duties between them.
