Calcutta, July 7 :     Unlike previous years, West Bengal chief minister and Left Front patriarch Jyoti Basu, who turns 87 tomorrow, is going to observe his birthday in a different manner. Basu, now holidaying in London, will spend tomorrow overseeing his granddaughter Mallika's marriage to Andre at a small church in Barkshire. 'Basu has no other programmes tomorrow except attending the marriage ceremony in Barkshire Church,' said Prasanta Roy, Basu's aide. The chief minister left for Israel on June 29 and has gone to London from there. He will be back on July 18. Roy said over phone from London that Basu, his son Chandan, Mallika's mother Doli, and her two sisters, Doyel and Koyel, were the only guests from Calcutta to attend the wedding ceremony. 'We have hardly any other guests from Calcutta barring a few members from the Basu family. The entire function is being organised from the bridegroom's side,' Roy said. Basu was unavailable for comment at St James Court hotel in London till late midnight. Mallika's grandmother Kamal Basu and Chandan's second wife will be conspicuous by their absence from tomorrow's grand function. Sources in Indira Bhavan, where Basu's wife is staying alone at the moment, said Mallika - Payel to her close circle - had called up grandma twice during the day to enquire about her health and seek her blessings. Payel, 22, who has just completed a journalism course in London, is engaged to 23-year old Andre, a photographer for quite a few years. 'We are happy that the marriage is being solemnised tomorrow,' said Jyotsna Panda, Doli's aide. 'Andre looks like an Englishman with a well-built physique. He is short but fair complexioned with bluish eyes and dark hair.' Panda said Andre had spent three days with boudi and didimani at Salt Lake when he came to Calcutta last October. 'Payel didimani came earlier here to spend her vacation and Jamai Babajivan joined her later,' she recounted. According to Panda, Boudi left for London with the youngest daughter Koyel on June 20 after completing the entire marketing on her own. Doyel didimani who is also studying in London joined them later. 'Boudi is coming back on July 16 but we have no idea whether the newly-wed couple is accompanying her,' Panda said, adding, 'However, we are expecting the newly-wed couple sometime next January.' The city will miss Basu on his 87th birthday. Indira Bhavan, which is normally visited by hundreds of people on the occasion, will remain deserted tomorrow. Transport minister Subhas Chakraborty, who organised Basu's 86th birthday, said: 'I am missing Basu very much. I had planned to make massive arrangements for celebrating Basu's 87th birthday this time. But his absence has spoilt the whole design.'
