CPI(M) General Secretary M. A. Baby's visible warmth toward All India Trinamool Congress (TMC) chief Mamata Banerjee at a recent INDIA bloc rally in New Delhi has reportedly triggered a sharp internal debate within sections of the Left Front, raising uncomfortable questions about whether national Opposition unity can coexist with an uncompromising fight against Trinamool in West Bengal. The unease, observers say, risks fracturing the relationship between the party's top leadership and its grassroots cadre.

The Image That Ignited the Debate

An unverified photograph from Sunday's INDIA bloc rally in New Delhi — circulating widely — reportedly shows Baby leaning in to whisper into Mamata's ear as she listens attentively, with a smile. The optics alone, according to Left insiders, would have been 'unbelievable' and 'abhorred' even in the recent past. Mamata's defining political project over the last decade-and-a-half has been dismantling West Bengal's Left Front bastion — a goal she accomplished in 2011, roughly 13 years after breaking away from the Indian National Congress (Congress).

The Fault Line Inside the Left

At the heart of the controversy is a strategic question: can the Left fight the Bharatiya Janata Party (BJP) nationally while simultaneously maintaining an adversarial posture against Trinamool in Bengal? Two schools of thought have emerged.

One camp argues that confronting the 'larger enemy' — the BJP — requires the Left to treat the 'enemy's enemy' as a temporary ally, even when that ally has historically been a regional opponent. Proponents point to how the CPI(M)'s central decision-making body previously sanctioned support to Congress in its fight against 'communal forces', suggesting ideological flexibility is not unprecedented. They further argue that withdrawing support from the Congress-led United Progressive Alliance (UPA) marked the beginning of the Left's sustained electoral erosion.

The opposing camp is equally vocal. It points to the failure of the Left-Congress alliance in West Bengal to mount a credible challenge against Trinamool during Mamata's heydays, as evidence that tactical alliances with ideologically inconvenient partners yield diminishing returns. This group also flags the structural contradiction: the Left coalition remains in direct electoral contest against a Congress-led alliance in Kerala, making a fully unified national posture difficult to sustain at the state level.

Baby's Line vs Karat's Legacy

Observers note that since taking charge of the CPI(M), Baby has placed considerable emphasis on 'anti-BJP unity', and his interactions with Mamata within the INDIA bloc framework have been characterised as 'cordial'. Within party circles, media reports suggest a section is already describing the new political direction as 'Baby steps' away from the strategic framework associated with veteran Marxist leader and former General Secretary Prakash Karat — who had long insisted on maintaining the Left's independent political identity, separate from both the BJP and the Congress.

For years, the Bengal Left maintained publicly that the BJP and Trinamool represented 'two sides of the same coin'. Senior Left leaders had argued that any political understanding with Mamata Banerjee would weaken their independent political space and confuse their cadre base — particularly in a state where the party alleges sustained atrocities on its supporters under her administration.

Grassroots Anxiety in Bengal

In West Bengal, Left workers who confronted Trinamool at the ground level during Mamata's tenure reportedly view the leadership's growing proximity with deep suspicion. Their concern is twofold: that blurred political messaging could further erode the Left's already diminished independent support base, and that it reinforces the perception that the party has accepted a secondary, support role in state politics rather than mounting a genuine revival.

The CPI(M)'s parliamentary presence today is a fraction of what it was at its peak, which many within the party acknowledge has made Opposition unity a strategic necessity rather than merely a tactical option. Whether that necessity can be communicated convincingly to workers on the ground in Bengal — where the wounds of post-2011 political violence remain fresh — will be the defining challenge for Baby's leadership in the months ahead.
