London, Aug 24 (IANS) Former Beatle Sir Paul McCartney's ex-wife Heather Mills is facing legal action from a civic council over her failure to remove a large marquee from her garden.

Mills is believed to have erected the tent at her $6.4 million (3.2 million pounds) home in East Sussex, England, for her 40th birthday party in January this year, reports Contactmusic.com.

The structure has remained in place ever since, prompting some of her neighbours to lodge objections with government officials.

The district council ruled in favour of the neighbours and signed an enforcement order in May in a bid to force Mills to take down the marquee, but the tent has yet to be removed.

Officials have now set Mills a deadline to get rid of it or they will take her to court.

'She has now been given a compliance date of Sep 20 to have the structure removed. If it is not done by that time we can start legal proceedings,' said a council spokesman.
